+
+<p>Although the Kudu server is written in C++ for performance and efficiency, developers can write
+client applications in C++, Java, or Python. To make it easier for Java developers to create
+reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests
+using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++,
+and without any complicated coordination around starting and stopping Kudu clusters for each test.
+This post describes how the new testing utilities work and how you can use them in your application
+tests.</p>

+
+<p>Note: It is possible this blog post could become outdated – for the latest documentation on using
+the JVM testing utilities see the
+<a href="https://kudu.apache.org/docs/developing.html#_jvm_based_integration_testing">Kudu documentation</a>.</p>
+
+<h3 id="requirements">Requirements</h3>
+
+<p>In order to use the new testing utilities, the following requirements must be met:</p>
+
+<ul>
+ <li>OS
+ <ul>
+ <li>macOS El Capitan (10.11) or later</li>
+ <li>CentOS 6.6+, Ubuntu 14.04+, or another recent distribution of Linux
+ <a href="https://kudu.apache.org/docs/installation.html#_prerequisites_and_requirements">supported by Kudu</a></li>
+ </ul>
+ </li>
+ <li>JVM
+ <ul>
+ <li>Java 8+</li>
+ <li>Note: Java 7+ is deprecated, but still supported</li>
+ </ul>
+ </li>
+ <li>Build Tool
+ <ul>
+ <li>Maven 3.1 or later, required to support the
+<a href="https://github.com/trustin/os-maven-plugin">os-maven-plugin</a></li>
+ <li>Gradle 2.1 or later, to support the
+<a href="https://github.com/google/osdetector-gradle-plugin">osdetector-gradle-plugin</a></li>
+ <li>Any other build tool that can download the correct jar from Maven</li>
+ </ul>
+ </li>
+</ul>
+
+<h3 id="build-configuration">Build Configuration</h3>
+
+<p>In order to use the Kudu testing utilities, add two dependencies to your classpath:</p>
+
+<ul>
+ <li>The <code>kudu-test-utils</code> dependency</li>
+ <li>The <code>kudu-binary</code> dependency</li>
+</ul>
+
+<p>The <code>kudu-test-utils</code> dependency has useful utilities for testing applications that use Kudu.
+Primarily, it provides the
+<a href="https://github.com/apache/kudu/blob/master/java/kudu-test-utils/src/main/java/org/apache/kudu/test/KuduTestHarness.java">KuduTestHarness class</a>
+to manage the lifecycle of a Kudu cluster for each test. The <code>KuduTestHarness</code> is a
+<a href="https://junit.org/junit4/javadoc/4.12/org/junit/rules/TestRule.html">JUnit TestRule</a>
+that not only starts and stops a Kudu cluster for each test, but also has methods to manage the
+cluster and get pre-configured <code>KuduClient</code> instances for use while testing.</p>
+
+<p>The <code>kudu-binary</code> dependency contains the native Kudu (server and command-line tool) binaries for
+the specified operating system. In order to download the right artifact for the running operating
+system it is easiest to use a plugin, such as the
+<a href="https://github.com/trustin/os-maven-plugin">os-maven-plugin</a> or
+<a href="https://github.com/google/osdetector-gradle-plugin">osdetector-gradle-plugin</a>, to detect the
+current runtime environment. The <code>KuduTestHarness</code> will automatically find and use the <code>kudu-binary</code>
+jar on the classpath.</p>
+
+<p>WARNING: The <code>kudu-binary</code> module should only be used to run Kudu for integration testing purposes.
+It should never be used to run an actual Kudu service, in production or development, because the
+<code>kudu-binary</code> module includes native security-related dependencies that have been copied from the
+build system and will not be patched when the operating system on the runtime host is patched.</p>
+
+<h4 id="maven-configuration">Maven Configuration</h4>
+
+<p>If you are using Maven to build your project, add the following entries to your project’s
+<code>pom.xml</code> file:</p>
+
+<div class="highlight"><pre><code class="language-xml" data-lang="xml"><span class="nt"><build></span>

+<h4 id="gradle-configuration">Gradle Configuration</h4>
+
+<p>If you are using Gradle to build your project, add the following entries to your project’s
+<code>build.gradle</code> file:</p>

+<span class="o">}</span></code></pre></div>
+
+<h2 id="test-setup">Test Setup</h2>
+
+<p>Once your project is configured correctly, you can start writing tests using the <code>kudu-test-utils</code>
+and <code>kudu-binary</code> artifacts. One line of code will ensure that each test automatically starts and
+stops a real Kudu cluster and that cluster logging is output through <code>slf4j</code>:</p>

+
+<p>Although the Kudu server is written in C++ for performance and efficiency, developers can write
+client applications in C++, Java, or Python. To make it easier for Java developers to create
+reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests
+using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++,
+and without any complicated coordination around starting and stopping Kudu clusters for each test.
+This post describes how the new testing utilities work and how you can use them in your application
+tests.</p>

- <p class="meta">Posted 31 Aug 2016 by Ara Abrahamian</p>
- </header>
- <div class="entry-content">
-
- <p>This post discusses the Kudu Flume Sink. First, I’ll give some background on why we considered
-using Kudu, what Flume does for us, and how Flume fits with Kudu in our project.</p>
-
-<h2 id="why-kudu">Why Kudu</h2>
-
-<p>Traditionally in the Hadoop ecosystem we’ve dealt with various <em>batch processing</em> technologies such
-as MapReduce and the many libraries and tools built on top of it in various languages (Apache Pig,
-Apache Hive, Apache Oozie and many others). The main problem with this approach is that it needs to
-process the whole data set in batches, again and again, as soon as new data gets added. Things get
-really complicated when a few such tasks need to get chained together, or when the same data set
-needs to be processed in various ways by different jobs, while all compete for the shared cluster
-resources.</p>
-
-<p>The opposite of this approach is <em>stream processing</em>: process the data as soon as it arrives, not
-in batches. Streaming systems such as Spark Streaming, Storm, Kafka Streams, and many others make
-this possible. But writing streaming services is not trivial. The streaming systems are becoming
-more and more capable and support more complex constructs, but they are not yet easy to use. All
-queries and processes need to be carefully planned and implemented.</p>
-
-<p>To summarize, <em>batch processing</em> is:</p>
-
-<ul>
- <li>file-based</li>
- <li>a paradigm that processes large chunks of data as a group</li>
- <li>high latency and high throughput, both for ingest and query</li>
- <li>typically easy to program, but hard to orchestrate</li>
- <li>well suited for writing ad-hoc queries, although they are typically high latency</li>
-</ul>
-
-<p>While <em>stream processing</em> is:</p>
-
-<ul>
- <li>a totally different paradigm, which involves single events and time windows instead of large groups of events</li>
- <li>still file-based and not a long-term database</li>
- <li>not batch-oriented, but incremental</li>
- <li>ultra-fast ingest and ultra-fast query (query results basically pre-calculated)</li>
- <li>not so easy to program, relatively easy to orchestrate</li>
- <li>impossible to write ad-hoc queries</li>
-</ul>
-
-<p>And a Kudu-based <em>near real-time</em> approach is:</p>
-
-<ul>
- <li>flexible and expressive, thanks to SQL support via Apache Impala (incubating)</li>
- <li>a table-oriented, mutable data store that feels like a traditional relational database</li>
- <li>very easy to program, you can even pretend it’s good old MySQL</li>
- <li>low-latency and relatively high throughput, both for ingest and query</li>
-</ul>
-
-<p>At Argyle Data, we’re dealing with complex fraud detection scenarios. We need to ingest massive
-amounts of data, run machine learning algorithms and generate reports. When we created our current
-architecture two years ago we decided to opt for a database as the backbone of our system. That
-database is Apache Accumulo. It’s a key-value based database which runs on top of Hadoop HDFS,
-quite similar to HBase but with some important improvements such as cell level security and ease
-of deployment and management. To enable querying of this data for quite complex reporting and
-analytics, we used Presto, a distributed query engine with a pluggable architecture open-sourced
-by Facebook. We wrote a connector for it to let it run queries against the Accumulo database. This
-architecture has served us well, but there were a few problems:</p>
-
-<ul>
- <li>we need to ingest even more massive volumes of data in real-time</li>
- <li>we need to perform complex machine-learning calculations on even larger data-sets</li>
- <li>we need to support ad-hoc queries, plus long-term data warehouse functionality</li>
-</ul>
-
-<p>So, we’ve started gradually moving the core machine-learning pipeline to a streaming based
-solution. This way we can ingest and process larger data-sets faster in the real-time. But then how
-would we take care of ad-hoc queries and long-term persistence? This is where Kudu comes in. While
-the machine learning pipeline ingests and processes real-time data, we store a copy of the same
-ingested data in Kudu for long-term access and ad-hoc queries. Kudu is our <em>data warehouse</em>. By
-using Kudu and Impala, we can retire our in-house Presto connector and rely on Impala’s
-super-fast query engine.</p>
-
-<p>But how would we make sure data is reliably ingested into the streaming pipeline <em>and</em> the
-Kudu-based data warehouse? This is where Apache Flume comes in.</p>
-
-<h2 id="why-flume">Why Flume</h2>
-
-<p>According to their <a href="http://flume.apache.org/">website</a> “Flume is a distributed, reliable, and
-available service for efficiently collecting, aggregating, and moving large amounts of log data.
-It has a simple and flexible architecture based on streaming data flows. It is robust and fault
-tolerant with tunable reliability mechanisms and many failover and recovery mechanisms.” As you
-can see, nowhere is Hadoop mentioned but Flume is typically used for ingesting data to Hadoop
-clusters.</p>
-
-<p><img src="https://blogs.apache.org/flume/mediaresource/ab0d50f6-a960-42cc-971e-3da38ba3adad" alt="png" /></p>
-
-<p>Flume has an extensible architecture. An instance of Flume, called an <em>agent</em>, can have multiple
-<em>channels</em>, with each having multiple <em>sources</em> and <em>sinks</em> of various types. Sources queue data
-in channels, which in turn write out data to sinks. Such <em>pipelines</em> can be chained together to
-create even more complex ones. There may be more than one agent and agents can be configured to
-support failover and recovery.</p>
-
-<p>Flume comes with a bunch of built-in types of channels, sources and sinks. Memory channel is the
-default (an in-memory queue with no persistence to disk), but other options such as Kafka- and
-File-based channels are also provided. As for the sources, Avro, JMS, Thrift, spooling directory
-source are some of the built-in ones. Flume also ships with many sinks, including sinks for writing
-data to HDFS, HBase, Hive, Kafka, as well as to other Flume agents.</p>
-
-<p>In the rest of this post I’ll go over the Kudu Flume sink and show you how to configure Flume to
-write ingested data to a Kudu table. The sink has been part of the Kudu distribution since the 0.8
-release and the source code can be found <a href="https://github.com/apache/kudu/tree/master/java/kudu-flume-sink">here</a>.</p>
-
-<h2 id="configuring-the-kudu-flume-sink">Configuring the Kudu Flume Sink</h2>
-
-<p>Here is a sample flume configuration file:</p>
-
-<pre><code>agent1.sources = source1
-agent1.channels = channel1
-agent1.sinks = sink1
-
-agent1.sources.source1.type = exec
-agent1.sources.source1.command = /usr/bin/vmstat 1
-agent1.sources.source1.channels = channel1
-
-agent1.channels.channel1.type = memory
-agent1.channels.channel1.capacity = 10000
-agent1.channels.channel1.transactionCapacity = 1000
-
-agent1.sinks.sink1.type = org.apache.flume.sink.kudu.KuduSink
-agent1.sinks.sink1.masterAddresses = localhost
-agent1.sinks.sink1.tableName = stats
-agent1.sinks.sink1.channel = channel1
-agent1.sinks.sink1.batchSize = 50
-agent1.sinks.sink1.producer = org.apache.kudu.flume.sink.SimpleKuduEventProducer
-</code></pre>
-
-<p>We define a source called <code>source1</code> which simply executes a <code>vmstat</code> command to continuously generate
-virtual memory statistics for the machine and queue events into an in-memory <code>channel1</code> channel,
-which in turn is used for writing these events to a Kudu table called <code>stats</code>. We are using
-<code>org.apache.kudu.flume.sink.SimpleKuduEventProducer</code> as the producer. <code>SimpleKuduEventProducer</code> is
-the built-in and default producer, but it’s implemented as a showcase for how to write Flume
-events into Kudu tables. For any serious functionality we’d have to write a custom producer. We
-need to make this producer and the <code>KuduSink</code> class available to Flume. We can do that by simply
-copying the <code>kudu-flume-sink-<VERSION>.jar</code> jar file from the Kudu distribution to the
-<code>$FLUME_HOME/plugins.d/kudu-sink/lib</code> directory in the Flume installation. The jar file contains
-<code>KuduSink</code> and all of its dependencies (including Kudu java client classes).</p>
-
-<p>At a minimum, the Kudu Flume Sink needs to know where the Kudu masters are
-(<code>agent1.sinks.sink1.masterAddresses = localhost</code>) and which Kudu table should be used for writing
-Flume events to (<code>agent1.sinks.sink1.tableName = stats</code>). The Kudu Flume Sink doesn’t create this
-table, it has to be created before the Kudu Flume Sink is started.</p>
-
-<p>You may also notice the <code>batchSize</code> parameter. Batch size is used for batching up to that many
-Flume events and flushing the entire batch in one shot. Tuning batchSize properly can have a huge
-impact on ingest performance of the Kudu cluster.</p>
-
-<p>Here is a complete list of KuduSink parameters:</p>
-
-<table>
- <thead>
- <tr>
- <th>Parameter Name</th>
- <th>Default</th>
- <th>Description</th>
- </tr>
- </thead>
- <tbody>
- <tr>
- <td>masterAddresses</td>
- <td>N/A</td>
- <td>Comma-separated list of “host:port” pairs of the masters (port optional)</td>
- </tr>
- <tr>
- <td>tableName</td>
- <td>N/A</td>
- <td>The name of the table in Kudu to write to</td>
- </tr>
- <tr>
- <td>producer</td>
- <td>org.apache.kudu.flume.sink.SimpleKuduEventProducer</td>
- <td>The fully qualified class name of the Kudu event producer the sink should use</td>
- </tr>
- <tr>
- <td>batchSize</td>
- <td>100</td>
- <td>Maximum number of events the sink should take from the channel per transaction, if available</td>
- </tr>
- <tr>
- <td>timeoutMillis</td>
- <td>30000</td>
- <td>Timeout period for Kudu operations, in milliseconds</td>
- </tr>
- <tr>
- <td>ignoreDuplicateRows</td>
- <td>true</td>
- <td>Whether to ignore errors indicating that we attempted to insert duplicate rows into Kudu</td>
- </tr>
- </tbody>
-</table>
-
-<p>Let’s take a look at the source code for the built-in producer class:</p>
-
-<pre><code class="language-java">public class SimpleKuduEventProducer implements KuduEventProducer {
- private byte[] payload;
- private KuduTable table;
- private String payloadColumn;
-
- public SimpleKuduEventProducer(){
- }
-
- @Override
- public void configure(Context context) {
- payloadColumn = context.getString("payloadColumn","payload");
- }
-
- @Override
- public void configure(ComponentConfiguration conf) {
- }
-
- @Override
- public void initialize(Event event, KuduTable table) {
- this.payload = event.getBody();
- this.table = table;
- }
-
- @Override
- public List<Operation> getOperations() throws FlumeException {
- try {
- Insert insert = table.newInsert();
- PartialRow row = insert.getRow();
- row.addBinary(payloadColumn, payload);
-
- return Collections.singletonList((Operation) insert);
- } catch (Exception e){
- throw new FlumeException("Failed to create Kudu Insert object!", e);
- }
- }
-
- @Override
- public void close() {
- }
-}
-</code></pre>
-
-<p><code>SimpleKuduEventProducer</code> implements the <code>org.apache.kudu.flume.sink.KuduEventProducer</code> interface,
-which itself looks like this:</p>
-
-<pre><code class="language-java">public interface KuduEventProducer extends Configurable, ConfigurableComponent {
- /**
- * Initialize the event producer.
- * @param event to be written to Kudu
- * @param table the KuduTable object used for creating Kudu Operation objects
- */
- void initialize(Event event, KuduTable table);
-
- /**
- * Get the operations that should be written out to Kudu as a result of this
- * event. This list is written to Kudu using the Kudu client API.
- * @return List of {@link org.kududb.client.Operation} which
- * are written as such to Kudu
- */
- List<Operation> getOperations();
-
- /*
- * Clean up any state. This will be called when the sink is being stopped.
- */
- void close();
-}
-</code></pre>
-
-<p><code>public void configure(Context context)</code> is called when an instance of our producer is instantiated
-by the KuduSink. SimpleKuduEventProducer’s implementation looks for a producer parameter named
-<code>payloadColumn</code> and uses its value (“payload” if not overridden in Flume configuration file) as the

-configured the KuduSink to listen for events generated from the <code>vmstat</code> command. Each output row
-from that command will be stored as a new row containing a <code>payload</code> column in the <code>stats</code> table.
-<code>SimpleKuduEventProducer</code> does not have any configuration parameters, but if it had any we would

-
-<p>The main producer logic resides in the <code>public List<Operation> getOperations()</code> method. In
-SimpleKuduEventProducer’s implementation we simply insert the binary body of the Flume event into
-the Kudu table. Here we call Kudu’s <code>newInsert()</code> to initiate an insert, but could have used
-<code>Upsert</code> if updating an existing row was also an option, in fact there’s another producer

+ <p class="meta">Posted 31 Aug 2016 by Ara Abrahamian</p>
+ </header>
+ <div class="entry-content">
+
+ <p>This post discusses the Kudu Flume Sink. First, I’ll give some background on why we considered
+using Kudu, what Flume does for us, and how Flume fits with Kudu in our project.</p>
+
+<h2 id="why-kudu">Why Kudu</h2>
+
+<p>Traditionally in the Hadoop ecosystem we’ve dealt with various <em>batch processing</em> technologies such
+as MapReduce and the many libraries and tools built on top of it in various languages (Apache Pig,
+Apache Hive, Apache Oozie and many others). The main problem with this approach is that it needs to
+process the whole data set in batches, again and again, as soon as new data gets added. Things get
+really complicated when a few such tasks need to get chained together, or when the same data set
+needs to be processed in various ways by different jobs, while all compete for the shared cluster
+resources.</p>
+
+<p>The opposite of this approach is <em>stream processing</em>: process the data as soon as it arrives, not
+in batches. Streaming systems such as Spark Streaming, Storm, Kafka Streams, and many others make
+this possible. But writing streaming services is not trivial. The streaming systems are becoming
+more and more capable and support more complex constructs, but they are not yet easy to use. All
+queries and processes need to be carefully planned and implemented.</p>
+
+<p>To summarize, <em>batch processing</em> is:</p>
+
+<ul>
+ <li>file-based</li>
+ <li>a paradigm that processes large chunks of data as a group</li>
+ <li>high latency and high throughput, both for ingest and query</li>
+ <li>typically easy to program, but hard to orchestrate</li>
+ <li>well suited for writing ad-hoc queries, although they are typically high latency</li>
+</ul>
+
+<p>While <em>stream processing</em> is:</p>
+
+<ul>
+ <li>a totally different paradigm, which involves single events and time windows instead of large groups of events</li>
+ <li>still file-based and not a long-term database</li>
+ <li>not batch-oriented, but incremental</li>
+ <li>ultra-fast ingest and ultra-fast query (query results basically pre-calculated)</li>
+ <li>not so easy to program, relatively easy to orchestrate</li>
+ <li>impossible to write ad-hoc queries</li>
+</ul>
+
+<p>And a Kudu-based <em>near real-time</em> approach is:</p>
+
+<ul>
+ <li>flexible and expressive, thanks to SQL support via Apache Impala (incubating)</li>
+ <li>a table-oriented, mutable data store that feels like a traditional relational database</li>
+ <li>very easy to program, you can even pretend it’s good old MySQL</li>
+ <li>low-latency and relatively high throughput, both for ingest and query</li>
+</ul>
+
+<p>At Argyle Data, we’re dealing with complex fraud detection scenarios. We need to ingest massive
+amounts of data, run machine learning algorithms and generate reports. When we created our current
+architecture two years ago we decided to opt for a database as the backbone of our system. That
+database is Apache Accumulo. It’s a key-value based database which runs on top of Hadoop HDFS,
+quite similar to HBase but with some important improvements such as cell level security and ease
+of deployment and management. To enable querying of this data for quite complex reporting and
+analytics, we used Presto, a distributed query engine with a pluggable architecture open-sourced
+by Facebook. We wrote a connector for it to let it run queries against the Accumulo database. This
+architecture has served us well, but there were a few problems:</p>
+
+<ul>
+ <li>we need to ingest even more massive volumes of data in real-time</li>
+ <li>we need to perform complex machine-learning calculations on even larger data-sets</li>
+ <li>we need to support ad-hoc queries, plus long-term data warehouse functionality</li>
+</ul>
+
+<p>So, we’ve started gradually moving the core machine-learning pipeline to a streaming based
+solution. This way we can ingest and process larger data-sets faster in the real-time. But then how
+would we take care of ad-hoc queries and long-term persistence? This is where Kudu comes in. While
+the machine learning pipeline ingests and processes real-time data, we store a copy of the same
+ingested data in Kudu for long-term access and ad-hoc queries. Kudu is our <em>data warehouse</em>. By
+using Kudu and Impala, we can retire our in-house Presto connector and rely on Impala’s
+super-fast query engine.</p>
+
+<p>But how would we make sure data is reliably ingested into the streaming pipeline <em>and</em> the
+Kudu-based data warehouse? This is where Apache Flume comes in.</p>
+
+<h2 id="why-flume">Why Flume</h2>
+
+<p>According to their <a href="http://flume.apache.org/">website</a> “Flume is a distributed, reliable, and
+available service for efficiently collecting, aggregating, and moving large amounts of log data.
+It has a simple and flexible architecture based on streaming data flows. It is robust and fault
+tolerant with tunable reliability mechanisms and many failover and recovery mechanisms.” As you
+can see, nowhere is Hadoop mentioned but Flume is typically used for ingesting data to Hadoop
+clusters.</p>
+
+<p><img src="https://blogs.apache.org/flume/mediaresource/ab0d50f6-a960-42cc-971e-3da38ba3adad" alt="png" /></p>
+
+<p>Flume has an extensible architecture. An instance of Flume, called an <em>agent</em>, can have multiple
+<em>channels</em>, with each having multiple <em>sources</em> and <em>sinks</em> of various types. Sources queue data
+in channels, which in turn write out data to sinks. Such <em>pipelines</em> can be chained together to
+create even more complex ones. There may be more than one agent and agents can be configured to
+support failover and recovery.</p>
+
+<p>Flume comes with a bunch of built-in types of channels, sources and sinks. Memory channel is the
+default (an in-memory queue with no persistence to disk), but other options such as Kafka- and
+File-based channels are also provided. As for the sources, Avro, JMS, Thrift, spooling directory
+source are some of the built-in ones. Flume also ships with many sinks, including sinks for writing
+data to HDFS, HBase, Hive, Kafka, as well as to other Flume agents.</p>
+
+<p>In the rest of this post I’ll go over the Kudu Flume sink and show you how to configure Flume to
+write ingested data to a Kudu table. The sink has been part of the Kudu distribution since the 0.8
+release and the source code can be found <a href="https://github.com/apache/kudu/tree/master/java/kudu-flume-sink">here</a>.</p>
+
+<h2 id="configuring-the-kudu-flume-sink">Configuring the Kudu Flume Sink</h2>
+
+<p>Here is a sample flume configuration file:</p>
+
+<pre><code>agent1.sources = source1
+agent1.channels = channel1
+agent1.sinks = sink1
+
+agent1.sources.source1.type = exec
+agent1.sources.source1.command = /usr/bin/vmstat 1
+agent1.sources.source1.channels = channel1
+
+agent1.channels.channel1.type = memory
+agent1.channels.channel1.capacity = 10000
+agent1.channels.channel1.transactionCapacity = 1000
+
+agent1.sinks.sink1.type = org.apache.flume.sink.kudu.KuduSink
+agent1.sinks.sink1.masterAddresses = localhost
+agent1.sinks.sink1.tableName = stats
+agent1.sinks.sink1.channel = channel1
+agent1.sinks.sink1.batchSize = 50
+agent1.sinks.sink1.producer = org.apache.kudu.flume.sink.SimpleKuduEventProducer
+</code></pre>
+
+<p>We define a source called <code>source1</code> which simply executes a <code>vmstat</code> command to continuously generate
+virtual memory statistics for the machine and queue events into an in-memory <code>channel1</code> channel,
+which in turn is used for writing these events to a Kudu table called <code>stats</code>. We are using
+<code>org.apache.kudu.flume.sink.SimpleKuduEventProducer</code> as the producer. <code>SimpleKuduEventProducer</code> is
+the built-in and default producer, but it’s implemented as a showcase for how to write Flume
+events into Kudu tables. For any serious functionality we’d have to write a custom producer. We
+need to make this producer and the <code>KuduSink</code> class available to Flume. We can do that by simply
+copying the <code>kudu-flume-sink-<VERSION>.jar</code> jar file from the Kudu distribution to the
+<code>$FLUME_HOME/plugins.d/kudu-sink/lib</code> directory in the Flume installation. The jar file contains
+<code>KuduSink</code> and all of its dependencies (including Kudu java client classes).</p>
+
+<p>At a minimum, the Kudu Flume Sink needs to know where the Kudu masters are
+(<code>agent1.sinks.sink1.masterAddresses = localhost</code>) and which Kudu table should be used for writing
+Flume events to (<code>agent1.sinks.sink1.tableName = stats</code>). The Kudu Flume Sink doesn’t create this
+table, it has to be created before the Kudu Flume Sink is started.</p>
+
+<p>You may also notice the <code>batchSize</code> parameter. Batch size is used for batching up to that many
+Flume events and flushing the entire batch in one shot. Tuning batchSize properly can have a huge
+impact on ingest performance of the Kudu cluster.</p>
+
+<p>Here is a complete list of KuduSink parameters:</p>
+
+<table>
+ <thead>
+ <tr>
+ <th>Parameter Name</th>
+ <th>Default</th>
+ <th>Description</th>
+ </tr>
+ </thead>
+ <tbody>
+ <tr>
+ <td>masterAddresses</td>
+ <td>N/A</td>
+ <td>Comma-separated list of “host:port” pairs of the masters (port optional)</td>
+ </tr>
+ <tr>
+ <td>tableName</td>
+ <td>N/A</td>
+ <td>The name of the table in Kudu to write to</td>
+ </tr>
+ <tr>
+ <td>producer</td>
+ <td>org.apache.kudu.flume.sink.SimpleKuduEventProducer</td>
+ <td>The fully qualified class name of the Kudu event producer the sink should use</td>
+ </tr>
+ <tr>
+ <td>batchSize</td>
+ <td>100</td>
+ <td>Maximum number of events the sink should take from the channel per transaction, if available</td>
+ </tr>
+ <tr>
+ <td>timeoutMillis</td>
+ <td>30000</td>
+ <td>Timeout period for Kudu operations, in milliseconds</td>
+ </tr>
+ <tr>
+ <td>ignoreDuplicateRows</td>
+ <td>true</td>
+ <td>Whether to ignore errors indicating that we attempted to insert duplicate rows into Kudu</td>
+ </tr>
+ </tbody>
+</table>
+
+<p>Let’s take a look at the source code for the built-in producer class:</p>
+
+<pre><code class="language-java">public class SimpleKuduEventProducer implements KuduEventProducer {
+ private byte[] payload;
+ private KuduTable table;
+ private String payloadColumn;
+
+ public SimpleKuduEventProducer(){
+ }
+
+ @Override
+ public void configure(Context context) {
+ payloadColumn = context.getString("payloadColumn","payload");
+ }
+
+ @Override
+ public void configure(ComponentConfiguration conf) {
+ }
+
+ @Override
+ public void initialize(Event event, KuduTable table) {
+ this.payload = event.getBody();
+ this.table = table;
+ }
+
+ @Override
+ public List<Operation> getOperations() throws FlumeException {
+ try {
+ Insert insert = table.newInsert();
+ PartialRow row = insert.getRow();
+ row.addBinary(payloadColumn, payload);
+
+ return Collections.singletonList((Operation) insert);
+ } catch (Exception e){
+ throw new FlumeException("Failed to create Kudu Insert object!", e);
+ }
+ }
+
+ @Override
+ public void close() {
+ }
+}
+</code></pre>
+
+<p><code>SimpleKuduEventProducer</code> implements the <code>org.apache.kudu.flume.sink.KuduEventProducer</code> interface,
+which itself looks like this:</p>
+
+<pre><code class="language-java">public interface KuduEventProducer extends Configurable, ConfigurableComponent {
+ /**
+ * Initialize the event producer.
+ * @param event to be written to Kudu
+ * @param table the KuduTable object used for creating Kudu Operation objects
+ */
+ void initialize(Event event, KuduTable table);
+
+ /**
+ * Get the operations that should be written out to Kudu as a result of this
+ * event. This list is written to Kudu using the Kudu client API.
+ * @return List of {@link org.kududb.client.Operation} which
+ * are written as such to Kudu
+ */
+ List<Operation> getOperations();
+
+ /*
+ * Clean up any state. This will be called when the sink is being stopped.
+ */
+ void close();
+}
+</code></pre>
+
+<p><code>public void configure(Context context)</code> is called when an instance of our producer is instantiated
+by the KuduSink. SimpleKuduEventProducer’s implementation looks for a producer parameter named
+<code>payloadColumn</code> and uses its value (“payload” if not overridden in Flume configuration file) as the
+column which will hold the value of the Flume event payload. If you recall from above, we had
+configured the KuduSink to listen for events generated from the <code>vmstat</code> command. Each output row
+from that command will be stored as a new row containing a <code>payload</code> column in the <code>stats</code> table.
+<code>SimpleKuduEventProducer</code> does not have any configuration parameters, but if it had any we would
+define them by prefixing it with <code>producer.</code> (<code>agent1.sinks.sink1.producer.parameter1</code> for
+example).</p>
+
+<p>The main producer logic resides in the <code>public List<Operation> getOperations()</code> method. In
+SimpleKuduEventProducer’s implementation we simply insert the binary body of the Flume event into
+the Kudu table. Here we call Kudu’s <code>newInsert()</code> to initiate an insert, but could have used
+<code>Upsert</code> if updating an existing row was also an option, in fact there’s another producer
+implementation available for doing just that: <code>SimpleKeyedKuduEventProducer</code>. Most probably you
+will need to write your own custom producer in the real world, but you can base your implementation
+on the built-in ones.</p>
+
+<p>In the future, we plan to add more flexible event producer implementations so that creation of a

+
+<p>Although the Kudu server is written in C++ for performance and efficiency, developers can write
+client applications in C++, Java, or Python. To make it easier for Java developers to create
+reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests
+using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++,
+and without any complicated coordination around starting and stopping Kudu clusters for each test.
+This post describes how the new testing utilities work and how you can use them in your application
+tests.</p>

+
+<h2 id="user-guide">User Guide</h2>
+
+<p>Note: It is possible this blog post could become outdated – for the latest documentation on using
+the JVM testing utilities see the
+<a href="https://kudu.apache.org/docs/developing.html#_jvm_based_integration_testing">Kudu documentation</a>.</p>
+
+<h3 id="requirements">Requirements</h3>
+
+<p>In order to use the new testing utilities, the following requirements must be met:</p>
+
+<ul>
+ <li>OS
+ <ul>
+ <li>macOS El Capitan (10.11) or later</li>
+ <li>CentOS 6.6+, Ubuntu 14.04+, or another recent distribution of Linux
+ <a href="https://kudu.apache.org/docs/installation.html#_prerequisites_and_requirements">supported by Kudu</a></li>
+ </ul>
+ </li>
+ <li>JVM
+ <ul>
+ <li>Java 8+</li>
+ <li>Note: Java 7+ is deprecated, but still supported</li>
+ </ul>
+ </li>
+ <li>Build Tool
+ <ul>
+ <li>Maven 3.1 or later, required to support the
+<a href="https://github.com/trustin/os-maven-plugin">os-maven-plugin</a></li>
+ <li>Gradle 2.1 or later, to support the
+<a href="https://github.com/google/osdetector-gradle-plugin">osdetector-gradle-plugin</a></li>
+ <li>Any other build tool that can download the correct jar from Maven</li>
+ </ul>
+ </li>
+</ul>
+
+<h3 id="build-configuration">Build Configuration</h3>
+
+<p>In order to use the Kudu testing utilities, add two dependencies to your classpath:</p>
+
+<ul>
+ <li>The <code>kudu-test-utils</code> dependency</li>
+ <li>The <code>kudu-binary</code> dependency</li>
+</ul>
+
+<p>The <code>kudu-test-utils</code> dependency has useful utilities for testing applications that use Kudu.
+Primarily, it provides the
+<a href="https://github.com/apache/kudu/blob/master/java/kudu-test-utils/src/main/java/org/apache/kudu/test/KuduTestHarness.java">KuduTestHarness class</a>
+to manage the lifecycle of a Kudu cluster for each test. The <code>KuduTestHarness</code> is a
+<a href="https://junit.org/junit4/javadoc/4.12/org/junit/rules/TestRule.html">JUnit TestRule</a>
+that not only starts and stops a Kudu cluster for each test, but also has methods to manage the
+cluster and get pre-configured <code>KuduClient</code> instances for use while testing.</p>
+
+<p>The <code>kudu-binary</code> dependency contains the native Kudu (server and command-line tool) binaries for
+the specified operating system. In order to download the right artifact for the running operating
+system it is easiest to use a plugin, such as the
+<a href="https://github.com/trustin/os-maven-plugin">os-maven-plugin</a> or
+<a href="https://github.com/google/osdetector-gradle-plugin">osdetector-gradle-plugin</a>, to detect the
+current runtime environment. The <code>KuduTestHarness</code> will automatically find and use the <code>kudu-binary</code>
+jar on the classpath.</p>
+
+<p>WARNING: The <code>kudu-binary</code> module should only be used to run Kudu for integration testing purposes.
+It should never be used to run an actual Kudu service, in production or development, because the
+<code>kudu-binary</code> module includes native security-related dependencies that have been copied from the
+build system and will not be patched when the operating system on the runtime host is patched.</p>

+
+<p>Once your project is configured correctly, you can start writing tests using the <code>kudu-test-utils</code>
+and <code>kudu-binary</code> artifacts. One line of code will ensure that each test automatically starts and
+stops a real Kudu cluster and that cluster logging is output through <code>slf4j</code>:</p>

+Testing Apache Kudu Applications on the JVM
+
+Although the Kudu server is written in C++ for performance and efficiency, developers can write
+client applications in C++, Java, or Python. To make it easier for Java developers to create
+reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests
+using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++,
+and without any complicated coordination around starting and stopping Kudu clusters for each test.
+This post describes how the new testing utilities work and how you can use them in your application
+tests.</summary></entry><entry><title>Apache Kudu 1.9.0 Released</title><link href="/2019/03/15/apache-kudu-1-9-0-release.html" rel="alternate" type="text/html" title="Apache Kudu 1.9.0 Released" /><published>2019-03-15T00:00:00-05:00</published><updated>2019-03-15T00:00:00-05:00</updated><id>/2019/03/15/apache-kudu-1-9-0-release</id><content type="html" xml:base="/2019/03/15/apache-kudu-1-9-0-release.html"><p>The Apache Kudu team is happy to announce the release of Kudu 1.9.0!</p>

- <li>Kudu servers can now tolerate short interruptions in NTP clock
-synchronization. NTP synchronization is still required when any Kudu daemon
-starts up.</li>
- <li>Tablet servers will no longer crash when a disk containing data blocks
-fails, unless that disk also stores WAL segments or tablet metadata. Instead
-of crashing, the tablet server will shut down any tablets that may have lost
-data locally and Kudu will re-replicate the affected tablets to another
-tablet server. More information can be found in the documentation under
-<a href="/releases/1.6.0/docs/administration.html#disk_failure_recovery">Recovering from Disk Failure</a>.</li>
- <li>Tablet server startup time has been improved significantly on servers
-containing large numbers of blocks.</li>
- <li>The Spark DataSource integration now can take advantage of scan locality for
-better scan performance. The scan will take place at the closest replica
-instead of going to the leader.</li>
- <li>Support for Spark 1 has been removed in Kudu 1.6.0 and now only Spark 2 is
-supported. Spark 1 support was deprecated in Kudu 1.5.0.</li>
- <li>HybridTime timestamp propagation now works in the Java client when using
-scan tokens.</li>
- <li>Tablet servers now consider the health of all replicas of a tablet before
-deciding to evict one. This can improve the stability of the Kudu cluster
-when multiple servers temporarily go down at the same time.</li>
- <li>A bug in the C++ client was fixed that could cause tablets to be erroneously
-pruned, or skipped, during certain scans, resulting in fewer results than
-expected being returned from queries. The bug only affected tables whose
-range partition columns are a proper prefix of the primary key.
-See <a href="https://issues.apache.org/jira/browse/KUDU-2173">KUDU-2173</a> for more
-information.</li>
