+# History of Apache Hadoop Ozone project
+
+Ozone development was started on a feature branch HDFS-7240 as part of the Apache Hadoop HDFS project. Based on the Jira information the first Ozone commit was the commit of [HDFS-8456 Ozone: Introduce STORAGE_CONTAINER_SERVICE as a new NodeType.](https://issues.apache.org/jira/browse/HDFS-8456) in May 2015.
+
+
+Ozone is an Object Store for Hadoop which is based on a lower level storage replication layer. This layer was originally called HDSL (Hadoop Distributed Storage Layer) and later renamed to HDDS (Hadoop Distributed Data Storage).
+
+Implementation of the generic storage layer began under [HDFS-11118](https://issues.apache.org/jira/browse/HDFS-11118) together with a iScsi/[jScsi](https://github.com/sebastiangraf/jSCSI) based block storage layer ("CBlock") introduced by [HDFS-11361](https://issues.apache.org/jira/browse/HDFS-11361).
+
+As a summary:
+
+ * HDDS (earlier HDSL): replicates huge binary _containers_ between datanodes
+ * Ozone: provides Object Store semantics with the help of HDDS
+ * CBlock: provides mountable volumes with the help of the HDDS layer (based on iScsi protocol)
+
+In the beginning of the year 2017 a new podling project was started inside [Apache Incubator](http://incubator.apache.org/): [Apache Ratis](https://ratis.apache.org/). Ratis is an embeddable RAFT protcol implementation it is which became the corner stone of consensus inside both Ozone and HDDS projects. (Started to [be used](https://issues.apache.org/jira/browse/HDFS-11519) by Ozone in March of 2017) 
+
+In the October of 2017 a [discussion](https://lists.apache.org/thread.html/3b5b65ce428f88299e6cb4c5d745ec65917490be9e417d361cc08d7e@%3Chdfs-dev.hadoop.apache.org%3E) has been started on hdfs-dev mailing list to merge the existing functionality to the Apache Hadoop trunk. After a long debate Owen O'Malley [suggested a consensus](https://lists.apache.org/thread.html/c85e5263dcc0ca1d13cbbe3bcfb53236784a39111b8c353f60582eb4@%3Chdfs-dev.hadoop.apache.org%3E) to merge it to the trunk but use separated release cycle:
+
+ > * HDSL become a subproject of Hadoop.
+ > * HDSL will release separately from Hadoop. Hadoop releases will notcontain HDSL and vice versa.
+ > * HDSL will get its own jira instance so that the release tags stay separate.
+ > * On trunk (as opposed to release branches) HDSL will be a separate module in Hadoop's source tree. This will enable the HDSL to work on their trunk and the Hadoop trunk without making releases for every change.
+ > * Hadoop's trunk will only build HDSL if a non-default profile is enabled. When Hadoop creates a release branch, the RM will delete the HDSL module from the branch.
+ > * HDSL will have their own Yetus checks and won't cause failures in the Hadoop patch check.
+
+This proposal was passed and after reorganizing the code (see HDFS-13258) and Ozone [has been voted](https://lists.apache.org/thread.html/ad0fe160ae84be97a0a87865059761ad7cd747be7b2fe060707d4f28@%3Chdfs-dev.hadoop.apache.org%3E) to be merged to the Hadoop trunk at the March of 2018.
+
+As the CBlock feature was not stable enough it was not merged and archived on a separated feature branch which was not synced with the newer Ozone/HDDS features. (Somewhat similar functionality is provided later with S3 Fuse file system and an S3 compatible REST gateway.)
+
+After the merge a new Jira project was created (HDDS) and the work was tracked under that project instead of child issues under HDFS-7240.
+
+In the next year multiple Ozone releases has been published in separated release package. The Ozone source release was developed on the Hadoop trunk, but the Ozone sources are removed from the main Hadoop releases.
+
+Originally, Ozone depended on the in-tree (SNAPSHOT) Hadoop artifacts. It was required to compile the core hadoop-hdfs/hadoop-common artifacts before compiling the Ozone subprojects. During the development this dependency was reduced more and more. With the 0.4.1 release this dependency has been totally removed and it became possible to compile Ozone with the help of the released Hadoop artifacts which made it possible to separate the development of Ozone from the main Hadoop trunk branch.
+
+In October 2019, the Ozone sources were moved out to the [apache/hadoop-ozone](https://github.com/apache/hadoop-ozone) git repository. During this move the git history was transformed to remove old YARN/HDFS/MAPREDUCE tasks. 
+
+ * The first git commit of the new repository is the commit which created the new maven subprojects for Ozone (before the trunk merge)
+ * Some of the oldest Ozone commits are available only from the Hadoop repository.
+ * Some newer HDDS commits have different commit hash in `hadoop` and `hadoop-ozone` repository.
+
+
+In March 2020, [Ozone 0.5.0 was released](https://hadoop.apache.org/ozone/release/0.5.0-beta/), the first release marked as _beta_tag (earlier releases were alpha).

+
+## Alternatives
+

+Ozone 的开发中大量地使用了 Docker,包括以下三种主要的应用场景:
+
+* __开发__:
+     * 我们使用 docker 来启动本地伪集群(docker 可以提供统一的环境,但是不需要创建镜像)。
+* __测试__:
+     * 我们从开发分支创建 docker 镜像,然后在 kubernetes 或其它容器编排系统上测试 ozone。
+     * 我们为每个发行版提供了 _apache/ozone_ 镜像,以方便用户体验 Ozone。
+     这些镜像 __不__ 应当在 __生产__ 中使用。
+
+<div class="alert alert-warning" role="alert">
+当在生产中使用容器方式部署 ozone 时,我们<b>强烈</b>建议你创建自己的镜像。请把所有自带的容器镜像和 k8s 资源文件当作示例指南,参考它们进行定制。
+</div>
+
+* __生产__:
+     * 我们提供了如何为生产集群创建 docker 镜像的文档。
+
+下面我们来详细地介绍一下各种应用场景:
+
+## 开发
+
+Ozone 安装包中包含了 docker-compose 的示例目录,用于方便地在本地机器启动 Ozone 集群。
+
+使用官方提供的发行包:
+
+```bash
+cd compose/ozone
+docker-compose up -d
+```
+
+本地构建方式:
+
+```bash
+cd  hadoop-ozone/dist/target/ozone-*/compose
+docker-compose up -d
+```
+
+这些 compose 环境文件是重要的工具,可以用来随时启动各种类型的 Ozone 集群。
+
+为了确保 compose 文件是最新的,我们提供了验收测试套件,套件会启动集群并检查其基本行为是否正常。
+
+验收测试也包含在发行包中,你可以在 `smoketest` 目录下找到各个测试的定义。
+
+你可以在任意 compose 目录进行测试,比如:
+
+```bash
+cd compose/ozone
+./test.sh
+```
+
+### 实现细节
+
+`compose` 测试都基于 apache/hadoop-runner 镜像,这个镜像本身并不包含任何 Ozone 的 jar 包或二进制文件,它只是提供其了启动 Ozone 的辅助脚本。
+
+hadoop-runner 提供了一个随处运行 Ozone 的固定环境,Ozone 分发包通过目录挂载包含在其中。
+
+(docker-compose 示例片段)
+
+```
+ scm:
+      image: apache/hadoop-runner:jdk11
+      volumes:
+         - ../..:/opt/hadoop
+      ports:
+         - 9876:9876
+
+```
+
+容器应该通过环境变量来进行配置,由于每个容器都应当设置相同的环境变量,我们在单独的文件中维护了一个环境变量列表:
+
+```
+ scm:
+      image: apache/hadoop-runner:jdk11
+      #...
+      env_file:
+          - ./docker-config
+```
+
+docker-config 文件中包含了所需环境变量的列表:
+
+```
+OZONE-SITE.XML_ozone.om.address=om
+OZONE-SITE.XML_ozone.om.http-address=om:9874
+OZONE-SITE.XML_ozone.scm.names=scm
+#...
+```
+
+你可以看到我们所使用的命名规范,根据这些环境变量的名字,`hadoop-runner` 基础镜像中的[脚本](https://github.com/apache/hadoop/tree/docker-hadoop-runner-latest/scripts) 会生成合适的 hadoop XML 配置文件(在我们这种情况下就是 `ozone-site.xml`)。
+
+`hadoop-runner` 镜像的[入口点](https://github.com/apache/hadoop/blob/docker-hadoop-runner-latest/scripts/starter
+.sh)包含了一个辅助脚本,这个辅助脚本可以根据环境变量触发上述的配置文件生成以及其它动作(比如初始化 SCM 和 OM 的存储、下载必要的 keytab 等)。
+
+## 测试 
+
+`docker-compose` 的方式应当只用于本地测试,不适用于多节点集群。要在多节点集群上使用容器,我们需要像 Kubernetes 这样的容器编排系统。
+
+Kubernetes 示例文件在 `kubernetes` 文件夹中。
+
+*请注意*:所有提供的镜像都使用 `hadoop-runner` 作为基础镜像,这个镜像中包含了所有测试环境所需的测试工具。对于生产环境,我们推荐用户使用自己的基础镜像创建可靠的镜像。
+
+### 发行包测试
+
+可以通过部署任意的示例集群来测试发行包:
+
+```bash
+cd kubernetes/examples/ozone
+kubectl apply -f
+```
+
+注意,在这个例子中会从 Docker Hub 下载最新的镜像。
+
+### 开发构建测试
+
+为了测试开发中的构建,你需要创建自己的镜像并上传到自己的 docker 仓库中:
+
+
+```bash
+mvn clean install -DskipTests -Pdocker-build,docker-push -Ddocker.image=myregistry:9000/name/ozone
+```
+
+所有生成的 kubernetes 资源文件都会使用这个镜像 (`image:` keys are adjusted during the build)
+
+```bash
+cd kubernetes/examples/ozone
+kubectl apply -f
+```
+
+## 生产
+
+<div class="alert alert-danger" role="alert">
+我们<b>强烈</b>推荐在生产集群使用自己的镜像,并根据实际的需求调整基础镜像、文件掩码、安全设置和用户设置。
+</div>
+
+你可以使用我们开发中所用的镜像作为示例:
+
+ * [基础镜像] (https://github.com/apache/hadoop/blob/docker-hadoop-runner-jdk11/Dockerfile)
+ * [完整镜像] (https://github.com/apache/hadoop/blob/trunk/hadoop-ozone/dist/src/main/docker/Dockerfile)
+
+ Dockerfile 中大部分内容都是可选的辅助功能,但如果要使用我们提供的 kubernetes 示例资源文件,你可能需要[这里](https://github.com/apache/hadoop/tree/docker-hadoop-runner-jdk11/scripts)的脚本。
+
+  * 两个 python 脚本将环境变量转化为实际的 hadoop XML 配置文件
+  * start.sh 根据环境变量执行 python 脚本(以及其它初始化工作)

+Ozone 的存储容器是一个自包含的超级块,容器中包含一系列的 Ozone 块,以及存储实际数据的磁盘文件,这是默认的存储容器格式。对于 Ozone 来说,容器只是提供了一个协议规范,它独立于具体的存储格式实现,换句话说,我们可以很容易扩展或引入新的容器实现格式。因此,上述格式应当被看作是 Ozone 存储容器的参考实现。
+
+## 理解 Ozone 中的块和容器
+
+当用户想要从 Ozone 中读取一个键时,用户向 OM 发送该键名,OM 会返回组成该键的块列表。
+
+每个 Ozone 块包含一个容器 ID 和一个本地 ID,下图展示了 Ozone 块的逻辑组成:
+
+![OzoneBlock](OzoneBlock.png)
+
+容器 ID 用来让用户发现容器的位置,容器位置的权威信息存储在 SCM 中。大部分情况下,OM 会缓存容器的位置信息,并会将它们随 Ozone 块一起返回给用户。
+
+当用户定位到容器的位置,即知道哪些数据节点包含这个容器后,用户会连接数据节点,然后读取由 _容器ID:本地ID_ 指定的数据流,换句话说,本地 ID 相当于容器内的索引,描述了我们应该读取哪个数据流。
+
+### 容器的位置发现
+
+SCM 如何获得容器的位置?这一点和现有的 HDFS 十分相似。数据节点会定期发送类似于块报告的容器报告,容器报告比块报告的内容简洁的多,比如,对于一个存储容量为 196 TB 的集群,Ozone 大概会拥有四万个容器,相比于 HDFS 的一百五十万个块,块报告数量缩减为四十分之一。
+
+这种间接管理的方式大大地提高了 Ozone 的扩展性,因为 SCM 需要处理的块数据大大减少,且命名服务(OM)作为一个独特的服务主体对于扩展 Ozone 具有重要意义。

+
+## Introduction
+
+This document explores how we can improve the Ozone volume semantics especially with respect to the S3 compatibility layer.
+
+## The Problems
+
+ 1. Unpriviliged users cannot enumerate volumes.
+ 2. The mapping of S3 buckets to Ozone volumes is confusing. Based on external feedback it's hard to understand the exact Ozone URL to be used.
+ 3. The volume name is not friendly and cannot be remembered by humans.
+ 4. Ozone buckets created via the native object store interface are not visible via the S3 gateway.
+ 5. We don't support the revocation of access keys.
+
+We explore some of these in more detail in subsequent sections.
+
+### Volume enumeration problem
+
+Currently when a user enumerates volumes, they see the list of volumes that they own. This means that when an unprivileged user enumerates volumes, it always gets any empty list. Instead users should be able to see all volumes that they have been granted read or write access to.
+
+This also has an impact on [ofs](https://issues.apache.org/jira/browse/HDDS-2665) which makes volumes appear as top-level directories.
+
+### S3 to HCFS path mapping problem
+
+Ozone has the semantics of volume *and* buckets while S3 has only buckets. To make it possible to use the same bucket both from Hadoop world and via S3 we need a mapping between them.
+
+Currently we maintain a map between the S3 buckets and Ozone volumes + buckets in `OmMetadataManagerImpl`
+
+```
+s3_bucket --> ozone_volume/ozone_bucket
+```
+ 
+The current implementation uses the `"s3" + s3UserName` string as the volume name and the `s3BucketName` as the bucket name. Where `s3UserName` is is the `DigestUtils.md5Hex(kerberosUsername.toLowerCase())`
+
+To create an S3 bucket and use it from o3fs, you should:
+
+1. Get your personal secret based on your kerberos keytab
+
+```
+> kinit -kt /etc/security/keytabs/testuser.keytab testuser/scm
+> ozone s3 getsecret
+awsAccessKey=testuser/scm@EXAMPLE.COM
+awsSecret=7a6d81dbae019085585513757b1e5332289bdbffa849126bcb7c20f2d9852092
+```
+
+2. Create the bucket with S3 cli
+
+```
+> export AWS_ACCESS_KEY_ID=testuser/scm@EXAMPLE.COM
+> export AWS_SECRET_ACCESS_KEY=7a6d81dbae019085585513757b1e5332289bdbffa849126bcb7c20f2d9852092
+> aws s3api --endpoint http://localhost:9878 create-bucket --bucket=bucket1
+```
+
+3. And identify the ozone path
+
+```
+> ozone s3 path bucket1
+Volume name for S3Bucket is : s3c89e813c80ffcea9543004d57b2a1239
+Ozone FileSystem Uri is : o3fs://bucket1.s3c89e813c80ffcea9543004d57b2a1239
+```
+
+## Proposed solution[1]
+
+### Supporting multiple access keys (#5 from the problem listing)
+
+Problem #5 can be easily supported with improving the `ozone s3` CLI. Ozone has a separated table for the S3 secrets and the API can be improved to handle multiple secrets for one specific kerberos user.
+
+### Solving the mapping problem (#2-4 from the problem listing)
+
+ 1. Let's always use `s3` volume for all the s3 buckets **if the bucket is created from the s3 interface**.
+
+This is an easy an fast method, but with this approach not all the volumes are avilable via the S3 interface. We need to provide a method to publish any of the ozone volumes / buckets.
+
+ 2. Let's improve the existing toolset to expose **any** Ozone volume/bucket as an s3 bucket. (Eg. expose `o3:/vol1/bucketx` as an S3 bucket `s3://foobar` )
+
+**Implementation**:
+
+ The first part is easy compared to the current implementation. We don't need any mapping table any more.
+
+ To implement the second (expose ozone buckets as s3 buckets) we have multiple options:
+
+   1. Store some metadata (** s3 bucket name **) on each of the buckets
+   2. Implement a **bind mount** mechanic which makes it possible to *mount* any volume/buckets to the specific "s3" volume.
+
+The first approach required a secondary cache table and it violates the naming hierarchy. The s3 bucket name is a global unique name, therefore it's more than just a single attribute on a specific object. It's more like an element in the hierachy. For this reason the second option is proposed:
+
+For example if the default s3 volume is `s3`
+
+ 1. Every new buckets created via s3 interface will be placed under the `/s3` volume
+ 2. Any existing **Ozone** buckets can be exposed with mounting it to s3: `ozone sh mount /vol1/bucket1 /s3/s3bucketname`
+
+**Lock contention problem**
+
+One possible problem with using just one volume is using the locks of the same volume for all the D3 buckets (thanks Xiaoyu). But this shouldn't be a big problem.
+
+ 1. We hold only a READ lock. Most of the time it can acquired without any contention (writing lock is required only to change owner / set quota)
+ 2. For symbolic link / bind mounts the read lock is only required for the first read. After that the lock of the referenced volume will be used. In case of any performance problem multiple volumes + bind mounts can be used.
+
+Note: Sunjay is added to the authors as the original proposal of this approach.
+
+## Alternative approaches and reasons to reject
+
+To solve the the _s3 bucket name to ozone bucket name mapping_ problem some other approaches are also considered. They are rejected but keeping them in this section together with the reasons to reject.
+
+
+### 1. Predefined volume mapping
+
+ 1. Let's support multiple `ACCESS_KEY_ID` for the same user.
+ 2. For each `ACCESS_KEY_ID` a volume name MUST be defined.
+ 3. Instead of using a specific mapping table, the `ACCESS_KEY_ID` would provide a **view** of the buckets in the specified volume.
+ 
+With this approach the used volume will be more visible and -- hopefully -- understandable.
+
+Instead of using `ozone s3 getsecret`, following commands would be used:
+
+ 1. `ozone s3 secret create --volume=myvolume`: To create a secret and use myvolume for all of these buckets
+ 2. `ozone s3 secret list`: To list all of the existing S3 secrets (available for the current user)
+ 3. `ozone s3 secret delete <ACCESS_KEY_ID`: To delete any secret
+
+The `AWS_ACCESS_KEY_ID` should be a random identifier instead of using a kerberos principal.
+
+ * __pro__: Easier to understand
+ * __con__: We should either have global unique bucket names or it will be possible to see two different buckets with
+ * __con__: It can be hard to remember which volumes are assigned to a specific ACCESS_KEY_ID
+ 
+### 3. String Magic
+
+We can try to make volume name visible for the S3 world by using some structured bucket names. Unfortunately the available separator characters are very limited:
+
+For example we can't use `/`
+
+```
+aws s3api create-bucket --bucket=vol1/bucket1
+
+Parameter validation failed:
+Invalid bucket name "vol1/bucket1": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$" or be an ARN matching the regex "^arn:(aws).*:s3:[a-z\-0-9]+:[0-9]{12}:accesspoint[/:][a-zA-Z0-9\-]{1,63}$"
+```
+
+But it's possible to use `volume-bucket` notion:
+
+```
+aws s3api create-bucket --bucket=vol1-bucket1
+```
+ * __pro__: Volume mapping is visible all the time.
+ * __con__: Harder to use any external tool with defaults (all the buckets should have at least one `-`)
+ * __con__: Hierarchy is not visble. The uniform way to separated elements in fs hierarchy is `/`. It can be confusing.
+ * 
+### 4. Remove volume From OzoneFs Paths
+
+We can also make volumes a lightweight *bucket group* object by removing it from the ozonefs path. With this approach we can use all the benefits of the volumes as an administration object but it would be removed from the `o3fs` path.
+
+ * __pro__: can be the most simple solution. Easy to understand as there are no more volumes in the path.
+ * __con__: Bigger change (all the API can't be modified to make volumes optional)
+ * __con__: Harder to dis-joint namespaces based on volumes. (With the current scheme, it's easier to delegate the responsibilties for one volumes to a different OM).
+ * __con__: We lose volumes as the top-level directories in `ofs` scheme.
+ * __con__: One level of hierarchy might not be enough in case of multi-tenancy.
+ * __con__: One level of hierarchy is not enough if we would like to provide separated level for users and admins 
+ * __con__: Hierarchical abstraction can be easier to manage and understand

+# Abstract
+
+ Recon is a monitoring and analytics server for Ozone. It can retrieve data from 
+ other components and store it and do historical queries (eg. out-of-disk-space time estimation).
+ 
+> Ozone Recon (short for reconnaissance) Service is, as the name suggests, meant to be eyes and ears of Ozone for the user. The first resort in understanding what is happening with Ozone.

+
+[Prometheus](https://prometheus.io/)是在[云原生计算基金会](https://www.cncf.io/)管理下开发的一款开源监控软件。
+
+Ozone 原生支持 Prometheus,各个组件会启动一个兼容 Prometheus 的指标端点,将所有可用的 hadoop 指标以 Prometheus 的格式导出发布。
+
+## 准备
+
+ 1. [安装启动]({{< ref "start/RunningViaDocker.zh.md" >}})一个 Ozone 集群。
+ 2. [下载](https://prometheus.io/download/#prometheus) Prometheus 二进制包。
+
+## 使用 Prometheus 进行监控
+
+* 你需要在 `ozone-site.xml` 文件中添加配置才可以启用 Prometheus 指标端点。
+
+ ```xml
+  <property>
+    <name>hdds.prometheus.endpoint.enabled</name>
+    <value>true</value>
+  </property>
+```
+
+_注意_: 对于基于 docker-compose 方式的伪集群,在 `docker-config` 文件中添加 `OZONE-SITE.XML_hdds.prometheus.endpoint.enabled=true`。
+
+* 重启 OM 和 SCM,检查端点:
+
+ * http://scm:9874/prom
+
+ * http://ozoneManager:9876/prom
+
+* 根据这两个端点,创建 prometheus.yaml 配置文件:
+
+```yaml
+global:
+  scrape_interval: 15s
+
+scrape_configs:
+  - job_name: ozone
+    metrics_path: /prom
+    static_configs:
+     - targets:
+        - "scm:9876"
+        - "ozoneManager:9874"
+```
+
+* 在 prometheus.yaml 文件所在目录启动 Prometheus:
+
+```bash
+prometheus
+```
+
+* 在 Prometheus 的 web ui 中查看目标:
+
+http://localhost:9090/targets
+
+![Prometheus 目标页面示例](prometheus.png)
+
+
+* 在 Prometheus web ui 中查看任意的指标,例如:
+For example:
+
+http://localhost:9090/graph?g0.range_input=1h&g0.expr=om_metrics_num_key_allocate&g0.tab=1
+
+![Prometheus 指标页面示例](prometheus-key-allocate.png)

+Ozone 发行包中包含了一个即开即用的容器化环境来试用 Ozone 和 Prometheus,在 `compose/ozoneperf` 目录下。
+
+```bash
+cd compose/ozoneperf
+docker-compose up -d

+审计解析器工具用于查询 Ozone 的审计日志。它会在指定的路径下创建一个 sqlite 数据库,若数据库已存在则不再创建。
+
+这个数据库只包含了一个名为 `audit` 的表,定义如下:
+
+CREATE TABLE IF NOT EXISTS audit (
+datetime text,
+level varchar(7),
+logger varchar(7),
+user text,
+ip text,
+op text,
+params text,
+result varchar(7),
+exception text,
+UNIQUE(datetime,level,logger,user,ip,op,params,result))
+
+用法:
+{{< highlight bash >}}
+ozone auditparser <数据库文件的路径> [命令] [参数]
+{{< /highlight >}}
+
+将审计日志加载到数据库:
+{{< highlight bash >}}
+ozone auditparser <数据库文件的路径> load <审计日志的路径>
+{{< /highlight >}}
+Load 命令会创建如上所述的审计表。
+
+运行一个自定义的只读查询:
+{{< highlight bash >}}
+ozone auditparser <数据库文件的路径> query <双引号括起来的 select 查询>
+{{< /highlight >}}
+
+审计解析起自带了一些模板(最常用的查询)
+
+运行模板查询:
+{{< highlight bash >}}
+ozone auditparser <数据库文件的路径 template <模板名称>
+{{< /highlight >}}
+
+Ozone 提供了以下模板:
+
+|模板名称|描述|SQL|
+|----------------|----------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------|
+|top5users|Top 5 users|select user,count(*) as total from audit group by user order by total DESC limit 5|

+
+测试是开发分布式系统中最重要的部分,我们提供了以下类型的测试。
+
+本页面给出了 Ozone 自带的测试工具。
+
+注意:我们还进行了其它测试(比如通过 Spark 或 Hive 进行的 TCP-DS、TCP-H),但因为它们是外部工具,所以没有在此列出。
+
+## 单元测试
+
+和每个 java 项目一样,我们的每个项目都包含传统的单元测试。
+
+## 集成测试(JUnit)
+
+传统的单元测试只能测试一个单元,但我们也有更高层次的单元测试。它们使用 `MiniOzoneCluster` 辅助方法在单元测试中启动守护进程(SCM、OM、数据节点)。
+
+从 maven 或 java 的角度来看,集成测试也只是普通的单元测试而已(使用了 JUnit 库),但为了解决一些依赖问题,我们将它们单独放在了 `hadoop-ozone/integration-test` 目录下。
+
+## 冒烟测试
+
+我们使用基于 docker-compose 的伪集群来运行不同配置的 Ozone,为了确保这些配置可用,我们在 https://robotframework.org/ 的帮助下实现了 _验收_ 测试。
+
+冒烟测试包含在发行包中(`./smoketest`),但 robot 文件只定义了运行命令行然后检查输出的测试。
+
+为了在不同环境(docker-compose、kubernetes)下运行冒烟测试,你需要定义如何启动容器,然后在正确的容器中执行正确的测试。
+
+这部分的测试包含在 `compose` 目录中(查看 `./compose/*/test.sh` 或者 `./compose/test-all.sh`)。
+
+例如,一种测试分发包的简单方法是:
+
+```
+cd compose/ozone
+./test.sh
+```
+
+## Blockade
+
+[Blockade](https://github.com/worstcase/blockade) 是一个测试网络故障和分片的工具(灵感来自于大名鼎鼎的[Jepsen 测试](https://jepsen.io/analyses))。
+
+Blockade 测试在其它测试的基础上实现,可以在分发包中的 `./blockade` 目录下进行测试。
+
+```
+cd blocakde
+pip install pytest==2.8.7,blockade
+python -m pytest -s .
+```
+
+更多细节查看 blockade 目录下的 README。
+
+## MiniChaosOzoneCluster
+
+这是一种在你的机器上获得[混沌](https://en.wikipedia.org/wiki/Chaos_engineering)的方法。它可以直接从源码启动一个 MiniOzoneCluster
+(会启动真实的守护进程),并随机杀死它。
+
+## Freon
+
+Freon 是 Ozone 发行包中包含的命令行应用,它是一个负载生成器,用于压力测试。
+
+例如:
+
+```
+ozone freon randomkeys --numOfVolumes=10 --numOfBuckets 10 --numOfKeys 10  --replicationType=RATIS --factor=THREE
+```
+
+```

+
+## Genesis
+
+Genesis 是一个微型的基准测试工具,它也包含在发行包中(`ozone genesis`),但是它不需要一个真实的集群,而是采用一种隔离的方法测试不同部分的代码(比如,将数据存储到本地基于 RocksDB 的键值存储中)。
+
+运行示例:
+
+```

+This helper project provides a reduced view to the Hadoop dependencies. Hadoop common by default depends on a lot of other projects
+which are not required for the parts used in Ozone.

+The exclude rules should be updated on each version bump. If Hadoop introduce new dependencies we need to exclude them (unless they are required).

+
+For the reference here are the minimal jar files wich are required by Ozone:

-The GNU General Public License (GPL)
-
-Version 2, June 1991
-
-Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-Everyone is permitted to copy and distribute verbatim copies of this license
-document, but changing it is not allowed.
-
-Preamble
-
-The licenses for most software are designed to take away your freedom to share
-and change it.  By contrast, the GNU General Public License is intended to
-guarantee your freedom to share and change free software--to make sure the
-software is free for all its users.  This General Public License applies to
-most of the Free Software Foundation's software and to any other program whose
-authors commit to using it.  (Some other Free Software Foundation software is
-covered by the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
-When we speak of free software, we are referring to freedom, not price.  Our
-General Public Licenses are designed to make sure that you have the freedom to
-distribute copies of free software (and charge for this service if you wish),
-that you receive source code or can get it if you want it, that you can change
-the software or use pieces of it in new free programs; and that you know you
-can do these things.
-
-To protect your rights, we need to make restrictions that forbid anyone to deny
-you these rights or to ask you to surrender the rights.  These restrictions
-translate to certain responsibilities for you if you distribute copies of the
-software, or if you modify it.
-
-For example, if you distribute copies of such a program, whether gratis or for
-a fee, you must give the recipients all the rights that you have.  You must
-make sure that they, too, receive or can get the source code.  And you must
-show them these terms so they know their rights.
-
-We protect your rights with two steps: (1) copyright the software, and (2)
-offer you this license which gives you legal permission to copy, distribute
-and/or modify the software.
-
-Also, for each author's protection and ours, we want to make certain that
-everyone understands that there is no warranty for this free software.  If the
-software is modified by someone else and passed on, we want its recipients to
-know that what they have is not the original, so that any problems introduced
-by others will not reflect on the original authors' reputations.
-
-Finally, any free program is threatened constantly by software patents.  We
-wish to avoid the danger that redistributors of a free program will
-individually obtain patent licenses, in effect making the program proprietary.
-To prevent this, we have made it clear that any patent must be licensed for
-everyone's free use or not licensed at all.
-
-The precise terms and conditions for copying, distribution and modification
-follow.
-
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-0. This License applies to any program or other work which contains a notice
-placed by the copyright holder saying it may be distributed under the terms of
-this General Public License.  The "Program", below, refers to any such program
-or work, and a "work based on the Program" means either the Program or any
-derivative work under copyright law: that is to say, a work containing the
-Program or a portion of it, either verbatim or with modifications and/or
-translated into another language.  (Hereinafter, translation is included
-without limitation in the term "modification".) Each licensee is addressed as
-"you".
-
-Activities other than copying, distribution and modification are not covered by
-this License; they are outside its scope.  The act of running the Program is
-not restricted, and the output from the Program is covered only if its contents
-constitute a work based on the Program (independent of having been made by
-running the Program).  Whether that is true depends on what the Program does.
-
-1. You may copy and distribute verbatim copies of the Program's source code as
-you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice and
-disclaimer of warranty; keep intact all the notices that refer to this License
-and to the absence of any warranty; and give any other recipients of the
-Program a copy of this License along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and you may
-at your option offer warranty protection in exchange for a fee.
-
-2. You may modify your copy or copies of the Program or any portion of it, thus
-forming a work based on the Program, and copy and distribute such modifications
-or work under the terms of Section 1 above, provided that you also meet all of
-these conditions:
-
-    a) You must cause the modified files to carry prominent notices stating
-    that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in whole or
-    in part contains or is derived from the Program or any part thereof, to be
-    licensed as a whole at no charge to all third parties under the terms of
-    this License.
-
-    c) If the modified program normally reads commands interactively when run,
-    you must cause it, when started running for such interactive use in the
-    most ordinary way, to print or display an announcement including an
-    appropriate copyright notice and a notice that there is no warranty (or
-    else, saying that you provide a warranty) and that users may redistribute
-    the program under these conditions, and telling the user how to view a copy
-    of this License.  (Exception: if the Program itself is interactive but does
-    not normally print such an announcement, your work based on the Program is
-    not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If identifiable
-sections of that work are not derived from the Program, and can be reasonably
-considered independent and separate works in themselves, then this License, and
-its terms, do not apply to those sections when you distribute them as separate
-works.  But when you distribute the same sections as part of a whole which is a
-work based on the Program, the distribution of the whole must be on the terms
-of this License, whose permissions for other licensees extend to the entire
-whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest your
-rights to work written entirely by you; rather, the intent is to exercise the
-right to control the distribution of derivative or collective works based on
-the Program.
-
-In addition, mere aggregation of another work not based on the Program with the
-Program (or with a work based on the Program) on a volume of a storage or
-distribution medium does not bring the other work under the scope of this
-License.
-
-3. You may copy and distribute the Program (or a work based on it, under
-Section 2) in object code or executable form under the terms of Sections 1 and
-2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable source
-    code, which must be distributed under the terms of Sections 1 and 2 above
-    on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three years, to
-    give any third party, for a charge no more than your cost of physically
-    performing source distribution, a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of Sections 1
-    and 2 above on a medium customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer to
-    distribute corresponding source code.  (This alternative is allowed only
-    for noncommercial distribution and only if you received the program in
-    object code or executable form with such an offer, in accord with
-    Subsection b above.)
-
-The source code for a work means the preferred form of the work for making
-modifications to it.  For an executable work, complete source code means all
-the source code for all modules it contains, plus any associated interface
-definition files, plus the scripts used to control compilation and installation
-of the executable.  However, as a special exception, the source code
-distributed need not include anything that is normally distributed (in either
-source or binary form) with the major components (compiler, kernel, and so on)
-of the operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the source
-code from the same place counts as distribution of the source code, even though
-third parties are not compelled to copy the source along with the object code.
-
-4. You may not copy, modify, sublicense, or distribute the Program except as
-expressly provided under this License.  Any attempt otherwise to copy, modify,
-sublicense or distribute the Program is void, and will automatically terminate
-your rights under this License.  However, parties who have received copies, or
-rights, from you under this License will not have their licenses terminated so
-long as such parties remain in full compliance.
-
-5. You are not required to accept this License, since you have not signed it.
-However, nothing else grants you permission to modify or distribute the Program
-or its derivative works.  These actions are prohibited by law if you do not
-accept this License.  Therefore, by modifying or distributing the Program (or
-any work based on the Program), you indicate your acceptance of this License to
-do so, and all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-6. Each time you redistribute the Program (or any work based on the Program),
-the recipient automatically receives a license from the original licensor to
-copy, distribute or modify the Program subject to these terms and conditions.
-You may not impose any further restrictions on the recipients' exercise of the
-rights granted herein.  You are not responsible for enforcing compliance by
-third parties to this License.
-
-7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues), conditions
-are imposed on you (whether by court order, agreement or otherwise) that
-contradict the conditions of this License, they do not excuse you from the
-conditions of this License.  If you cannot distribute so as to satisfy
-simultaneously your obligations under this License and any other pertinent
-obligations, then as a consequence you may not distribute the Program at all.
-For example, if a patent license would not permit royalty-free redistribution
-of the Program by all those who receive copies directly or indirectly through
-you, then the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply and
-the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any patents or
-other property right claims or to contest validity of any such claims; this
-section has the sole purpose of protecting the integrity of the free software
-distribution system, which is implemented by public license practices.  Many
-people have made generous contributions to the wide range of software
-distributed through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing to
-distribute software through any other system and a licensee cannot impose that
-choice.
-
-This section is intended to make thoroughly clear what is believed to be a
-consequence of the rest of this License.
-
-8. If the distribution and/or use of the Program is restricted in certain
-countries either by patents or by copyrighted interfaces, the original
-copyright holder who places the Program under this License may add an explicit
-geographical distribution limitation excluding those countries, so that
-distribution is permitted only in or among countries not thus excluded.  In
-such case, this License incorporates the limitation as if written in the body
-of this License.
-
-9. The Free Software Foundation may publish revised and/or new versions of the
-General Public License from time to time.  Such new versions will be similar in
-spirit to the present version, but may differ in detail to address new problems
-or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any later
-version", you have the option of following the terms and conditions either of
-that version or of any later version published by the Free Software Foundation.
-If the Program does not specify a version number of this License, you may
-choose any version ever published by the Free Software Foundation.
-
-10. If you wish to incorporate parts of the Program into other free programs
-whose distribution conditions are different, write to the author to ask for
-permission.  For software which is copyrighted by the Free Software Foundation,
-write to the Free Software Foundation; we sometimes make exceptions for this.
-Our decision will be guided by the two goals of preserving the free status of
-all derivatives of our free software and of promoting the sharing and reuse of
-software generally.
-
-NO WARRANTY
-
-11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
-THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN OTHERWISE
-STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
-PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
-INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
-FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND
-PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE,
-YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
-ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
-PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
-INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
-BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
-OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-END OF TERMS AND CONDITIONS
-
-How to Apply These Terms to Your New Programs
-
-If you develop a new program, and you want it to be of the greatest possible
-use to the public, the best way to achieve this is to make it free software
-which everyone can redistribute and change under these terms.
-
-To do so, attach the following notices to the program.  It is safest to attach
-them to the start of each source file to most effectively convey the exclusion
-of warranty; and each file should have at least the "copyright" line and a
-pointer to where the full notice is found.
-
-    One line to give the program's name and a brief idea of what it does.
-
-    Copyright (C) <year> <name of author>
-
-    This program is free software; you can redistribute it and/or modify it
-    under the terms of the GNU General Public License as published by the Free
-    Software Foundation; either version 2 of the License, or (at your option)
-    any later version.

-    This program is distributed in the hope that it will be useful, but WITHOUT
-    ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
-    FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for

-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc., 59
-    Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this when it
-starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
-    with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free
-    software, and you are welcome to redistribute it under certain conditions;
-    type 'show c' for details.
-
-The hypothetical commands 'show w' and 'show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may be
-called something other than 'show w' and 'show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.  Here
-is a sample; alter the names:
-
-    Yoyodyne, Inc., hereby disclaims all copyright interest in the program

-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General Public
-License instead of this License.
-
-
-"CLASSPATH" EXCEPTION TO THE GPL
-
-Certain source files distributed by Oracle America and/or its affiliates are
-subject to the following clarification and special exception to the GPL, but
-only where Oracle has expressly included in the particular source file's header
-the words "Oracle designates this particular file as subject to the "Classpath"
-exception as provided by Oracle in the LICENSE file that accompanied this code."
-
-    Linking this library statically or dynamically with other modules is making
-    a combined work based on this library.  Thus, the terms and conditions of
-    the GNU General Public License cover the whole combination.
-
-    As a special exception, the copyright holders of this library give you
-    permission to link this library with independent modules to produce an
-    executable, regardless of the license terms of these independent modules,
-    and to copy and distribute the resulting executable under terms of your
-    choice, provided that you also meet, for each linked independent module,
-    the terms and conditions of the license of that module.  An independent
-    module is a module which is not derived from or based on this library.  If
-    you modify this library, you may extend this exception to your version of
-    the library, but you are not obligated to do so.  If you do not wish to do
-    so, delete this exception statement from your version.

-Version 2, June 1991
-
-Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-Everyone is permitted to copy and distribute verbatim copies of this license
-document, but changing it is not allowed.
-
-Preamble
-
-The licenses for most software are designed to take away your freedom to share
-and change it.  By contrast, the GNU General Public License is intended to
-guarantee your freedom to share and change free software--to make sure the
-software is free for all its users.  This General Public License applies to
-most of the Free Software Foundation's software and to any other program whose
-authors commit to using it.  (Some other Free Software Foundation software is
-covered by the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
-When we speak of free software, we are referring to freedom, not price.  Our
-General Public Licenses are designed to make sure that you have the freedom to
-distribute copies of free software (and charge for this service if you wish),
-that you receive source code or can get it if you want it, that you can change
-the software or use pieces of it in new free programs; and that you know you
-can do these things.
-
-To protect your rights, we need to make restrictions that forbid anyone to deny
-you these rights or to ask you to surrender the rights.  These restrictions
-translate to certain responsibilities for you if you distribute copies of the
-software, or if you modify it.
-
-For example, if you distribute copies of such a program, whether gratis or for
-a fee, you must give the recipients all the rights that you have.  You must
-make sure that they, too, receive or can get the source code.  And you must
-show them these terms so they know their rights.
-
-We protect your rights with two steps: (1) copyright the software, and (2)
-offer you this license which gives you legal permission to copy, distribute
-and/or modify the software.
-
-Also, for each author's protection and ours, we want to make certain that
-everyone understands that there is no warranty for this free software.  If the
-software is modified by someone else and passed on, we want its recipients to
-know that what they have is not the original, so that any problems introduced
-by others will not reflect on the original authors' reputations.
-
-Finally, any free program is threatened constantly by software patents.  We
-wish to avoid the danger that redistributors of a free program will
-individually obtain patent licenses, in effect making the program proprietary.
-To prevent this, we have made it clear that any patent must be licensed for
-everyone's free use or not licensed at all.
-
-The precise terms and conditions for copying, distribution and modification
-follow.
-
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-0. This License applies to any program or other work which contains a notice
-placed by the copyright holder saying it may be distributed under the terms of
-this General Public License.  The "Program", below, refers to any such program
-or work, and a "work based on the Program" means either the Program or any
-derivative work under copyright law: that is to say, a work containing the
-Program or a portion of it, either verbatim or with modifications and/or
-translated into another language.  (Hereinafter, translation is included
-without limitation in the term "modification".) Each licensee is addressed as
-"you".
-
-Activities other than copying, distribution and modification are not covered by
-this License; they are outside its scope.  The act of running the Program is
-not restricted, and the output from the Program is covered only if its contents
-constitute a work based on the Program (independent of having been made by
-running the Program).  Whether that is true depends on what the Program does.
-
-1. You may copy and distribute verbatim copies of the Program's source code as
-you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice and
-disclaimer of warranty; keep intact all the notices that refer to this License
-and to the absence of any warranty; and give any other recipients of the
-Program a copy of this License along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and you may
-at your option offer warranty protection in exchange for a fee.
-
-2. You may modify your copy or copies of the Program or any portion of it, thus
-forming a work based on the Program, and copy and distribute such modifications
-or work under the terms of Section 1 above, provided that you also meet all of
-these conditions:
-
-    a) You must cause the modified files to carry prominent notices stating
-    that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in whole or
-    in part contains or is derived from the Program or any part thereof, to be
-    licensed as a whole at no charge to all third parties under the terms of
-    this License.
-
-    c) If the modified program normally reads commands interactively when run,
-    you must cause it, when started running for such interactive use in the
-    most ordinary way, to print or display an announcement including an
-    appropriate copyright notice and a notice that there is no warranty (or
-    else, saying that you provide a warranty) and that users may redistribute
-    the program under these conditions, and telling the user how to view a copy
-    of this License.  (Exception: if the Program itself is interactive but does
-    not normally print such an announcement, your work based on the Program is
-    not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If identifiable
-sections of that work are not derived from the Program, and can be reasonably
-considered independent and separate works in themselves, then this License, and
-its terms, do not apply to those sections when you distribute them as separate
-works.  But when you distribute the same sections as part of a whole which is a
-work based on the Program, the distribution of the whole must be on the terms
-of this License, whose permissions for other licensees extend to the entire
-whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest your
-rights to work written entirely by you; rather, the intent is to exercise the
-right to control the distribution of derivative or collective works based on
-the Program.
-
-In addition, mere aggregation of another work not based on the Program with the
-Program (or with a work based on the Program) on a volume of a storage or
-distribution medium does not bring the other work under the scope of this
-License.
-
-3. You may copy and distribute the Program (or a work based on it, under
-Section 2) in object code or executable form under the terms of Sections 1 and
-2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable source
-    code, which must be distributed under the terms of Sections 1 and 2 above
-    on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three years, to
-    give any third party, for a charge no more than your cost of physically
-    performing source distribution, a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of Sections 1
-    and 2 above on a medium customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer to
-    distribute corresponding source code.  (This alternative is allowed only
-    for noncommercial distribution and only if you received the program in
-    object code or executable form with such an offer, in accord with
-    Subsection b above.)

-from a designated place, then offering equivalent access to copy the source
-code from the same place counts as distribution of the source code, even though
-third parties are not compelled to copy the source along with the object code.
-

-expressly provided under this License.  Any attempt otherwise to copy, modify,
-sublicense or distribute the Program is void, and will automatically terminate
-your rights under this License.  However, parties who have received copies, or
-rights, from you under this License will not have their licenses terminated so
-long as such parties remain in full compliance.

+#Overview
+
+libo3fs is a JNI based C API for Ozone File System. It provides with read and write functionality on OzoneFileSystem. It also uses some functions from HDFS(Hadoop Distributed File System) for which it uses libhdfs, which is a JNI based C API for Hadoop’s Distributed File System (HDFS). It provides C APIs to a subset of the HDFS APIs to manipulate HDFS files and the filesystem. libhdfs is part of the Hadoop distribution and comes pre-compiled in $HADOOP_HDFS_HOME/lib/native/libhdfs.so .
+
+#The APIs
+
+The libo3fs APIs are a subset of the Ozone FileSystem APIs. The header file for libo3fs describes each API in detail and is available in ${OZONE_HOME}/native-client/libo3fs/o3fs.h.
+
+#Requirements:
+
+1.Hadoop with compiled libhdfs.so
+2.Linux kernel > 2.6.9 
+3.Compiled Ozone
+
+#Compilation
+
+      1.Compilation of .c files
+            In libo3fs directory there is one file o3fs.c.
+
+                Execute the following command to compile it: 
+
+           gcc -fPIC -pthread -I {OZONE_HOME}/native-client/libo3fs -I {HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/include -g -c o3fs.c
+           In the libo3fs-examples directory there are two .c files: libo3fs_read.c and libo3fs_write.c.
+
+               Execute the following command to compile libo3fs_read.c and libo3fs_write.c:
+
+           gcc -fPIC -pthread -I {OZONE_HOME}/native-client/libo3fs -I {HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/include -g -c libo3fs_read.c               
+           gcc -fPIC -pthread -I {OZONE_HOME}/native-client/libo3fs -I {HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/include -g -c libo3fs_write.c
+
+      2. Generation of libo3fs.so
+           Execute the following command to generate a .so:
+
+           gcc -shared o3fs.o hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs/mybuild/hdfs.o -o libo3fs.so.
+
+      3. Generation of binary(executable)
+           Two binaries have to be generated namely o3fs_read and o3fs_write.
+           Execute the following command to generate o3fs_red:
+
+           gcc -L {HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/target/native/target/usr/local/lib -o o3fs_read libo3fs_read.o -lhdfs -pthread -L/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre/lib/amd64/server -ljvm -L {OZONE_HOME}/native-client/libo3fs -lo3fs
+           
+           Execute the following command to execute o3fs_write:
+
+           gcc -L {HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/target/native/target/usr/local/lib -o o3fs_write libo3fs_write.o -lhdfs -pthread -L/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08- 0.el7_7.x86_64/jre/lib/amd64/server -ljvm -L {OZONE_HOME}/native-client/libo3fs -lo3fs
+
+#Deploying
+
+In root shell execute the following:
+
+    ./o3fs_write filename file_size buffer_size host_name port_number bucket_name volume_name
+
+For example
+
+    ./o3fs_write file1 100 100 127.0.0.1 9862 bucket4 vol4 , where file1 is name of the file, 100 is file size and buffer size, "127.0.0.1 is host", 9862 is the port number, "bucket4" is bucket name and "vol4" is the volume name.
+
+#Common Problems:
+
+CLASSPATH is not set. CLASSPATH can be set using the following command:
+ 
+           export CLASSPATH=$({OZONE_HOME}/hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/bin/ozone classpath hadoop-ozone-filesystem --glob)
+
+           export CLASSPATH=$CLASSPATH:{OZONE_HOME}/hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/share/ozone/lib/hadoop-ozone-filesystem-0.5.0-SNAPSHOT.jar
+
+LD_LIBRARY_PATH is not set. LD_LIBRARY_PATH can be set using the following command:  
+
+           export LD_LIBRARY_PATH={HADOOP_HOME}/hadoop-hdfs-project/hadoop-hdfs-native-client/target/native/target/usr/local/lib:
+                  /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre/lib/amd64/server:
+                  {OZONE_HOME}/native-client/libo3fs
+
+Ozone-site.xml is not configured. Save the minimal snippet to hadoop-ozone/dist/target/ozone-*/etc/hadoop/ozone-site.xml in the compiled distribution.
