| <h1>Notebook storage options for Apache Zeppelin</h1> |
| |
| <div id="toc"></div> |
| |
| <h2>Overview</h2> |
| |
| <p>Apache Zeppelin has a pluggable notebook storage mechanism controlled by <code>zeppelin.notebook.storage</code> configuration option with multiple implementations. |
| There are few notebook storage systems available for a use out of the box:</p> |
| |
| <ul> |
| <li>(default) use local file system and version it using local Git repository - <code>GitNotebookRepo</code></li> |
| <li>all notes are saved in the notebook folder in your local File System - <code>VFSNotebookRepo</code></li> |
| <li>storage using Amazon S3 service - <code>S3NotebookRepo</code></li> |
| <li>storage using Azure service - <code>AzureNotebookRepo</code></li> |
| </ul> |
| |
| <p>Multiple storage systems can be used at the same time by providing a comma-separated list of the class-names in the configuration. |
| By default, only first two of them will be automatically kept in sync by Zeppelin.</p> |
| |
| <p></br></p> |
| |
| <h2>Notebook Storage in local Git repository <a name="Git"></a></h2> |
| |
| <p>To enable versioning for all your local notebooks though a standard Git repository - uncomment the next property in <code>zeppelin-site.xml</code> in order to use GitNotebookRepo class:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text"><property> |
| <name>zeppelin.notebook.storage</name> |
| <value>org.apache.zeppelin.notebook.repo.GitNotebookRepo</value> |
| <description>notebook persistence layer implementation</description> |
| </property> |
| </code></pre></div> |
| <p></br></p> |
| |
| <h2>Notebook Storage in S3 <a name="S3"></a></h2> |
| |
| <p>Notebooks may be stored in S3, and optionally encrypted. The <a href="https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html"><code>DefaultAWSCredentialsProviderChain</code></a> credentials provider is used for credentials and checks the following:</p> |
| |
| <ul> |
| <li>The <code>AWS_ACCESS_KEY_ID</code> and <code>AWS_SECRET_ACCESS_KEY</code> environment variables</li> |
| <li>The <code>aws.accessKeyId</code> and <code>aws.secretKey</code> Java System properties</li> |
| <li>Credential profiles file at the default location (<code>~/.aws/credentials</code>) used by the AWS CLI</li> |
| <li>Instance profile credentials delivered through the Amazon EC2 metadata service</li> |
| </ul> |
| |
| <p></br> |
| The following folder structure will be created in S3:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">s3://bucket_name/username/notebook-id/ |
| </code></pre></div> |
| <p>Configure by setting environment variables in the file <strong>zeppelin-env.sh</strong>:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">export ZEPPELIN_NOTEBOOK_S3_BUCKET = bucket_name |

| <description>versioned notebook persistence layer implementation</description> |
| </property> |
| </code></pre></div> |
| <h3>Data Encryption in S3</h3> |
| |
| <h4>AWS KMS encryption keys</h4> |
| |
| <p>To use an <a href="https://aws.amazon.com/kms/">AWS KMS</a> encryption key to encrypt notebooks, set the following environment variable in the file <strong>zeppelin-env.sh</strong>:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">export ZEPPELIN_NOTEBOOK_S3_KMS_KEY_ID = kms-key-id |
| </code></pre></div> |
| <p>Or using the following setting in <strong>zeppelin-site.xml</strong>:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text"><property> |
| <name>zeppelin.notebook.s3.kmsKeyID</name> |
| <value>AWS-KMS-Key-UUID</value> |
| <description>AWS KMS key ID used to encrypt notebook data in S3</description> |
| </property> |
| </code></pre></div> |
| <p>In order to set custom KMS key region, set the following environment variable in the file <strong>zeppelin-env.sh</strong>:</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">export ZEPPELIN_NOTEBOOK_S3_KMS_KEY_REGION = kms-key-region |
| </code></pre></div> |
| <p>Or using the following setting in <strong>zeppelin-site.xml</strong>:</p> |
