+
+<p>Let’s use Eclipse to attach a remote debugger to a Samza container. If you’re an IntelliJ user, you’ll have to fill in the blanks, but the process should be pretty similar. This tutorial assumes you’ve already run through the <a href="../../../startup/hello-samza/0.8/">Hello Samza</a> tutorial.</p>
+
+<h3 id="get-the-code">Get the Code</h3>
+
+<p>Start by checking out Samza, so we have access to the source.</p>
+
+<div class="highlight"><pre><code class="bash">git clone http://git-wip-us.apache.org/repos/asf/incubator-samza.git</code></pre></div>
+
+<p>Next, grab hello-samza.</p>
+
+<div class="highlight"><pre><code class="bash">git clone git://git.apache.org/incubator-samza-hello-samza.git</code></pre></div>
+
+<h3 id="setup-the-environment">Setup the Environment</h3>
+
+<p>Now, let’s setup the Eclipse project files.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd </span>incubator-samza
+./gradlew eclipse</code></pre></div>
+
+<p>Let’s also release Samza to Maven’s local repository, so hello-samza has access to the JARs that it needs.</p>
+
+<div class="highlight"><pre><code class="bash">./gradlew -PscalaVersion<span class="o">=</span>2.9.2 clean publishToMavenLocal</code></pre></div>
+
+<p>Next, open Eclipse, and import the Samza source code into your workspace: “File” > “Import” > “Existing Projects into Workspace” > “Browse”. Select ‘incubator-samza’ folder, and hit ‘finish’.</p>
+
+<h3 id="enable-remote-debugging">Enable Remote Debugging</h3>
+
+<p>Now, go back to the hello-samza project, and edit ./src/main/config/wikipedia-feed.properties to add the following line:</p>
+
+<div class="highlight"><pre><code class="jproperties"><span class="na">task.opts</span><span class="o">=</span><span class="s">-agentlib:jdwp=transport=dt_socket,address=localhost:9009,server=y,suspend=y</span></code></pre></div>
+
+<p>The <a href="../../documentation/0.8/jobs/configuration-table.html">task.opts</a> configuration parameter is a way to override Java parameters at runtime for your Samza containers. In this example, we’re setting the agentlib parameter to enable remote debugging on localhost, port 9009. In a more realistic environment, you might also set Java heap settings (-Xmx, -Xms, etc), as well as garbage collection and logging settings.</p>
+
+<p><em>NOTE: If you’re running multiple Samza containers on the same machine, there is a potential for port collisions. You must configure your task.opts to assign different ports for different Samza jobs. If a Samza job has more than one container (e.g. if you’re using YARN with yarn.container.count=2), those containers must be run on different machines.</em></p>
+
+<h3 id="start-the-grid">Start the Grid</h3>
+
+<p>Now that the Samza job has been setup to enable remote debugging when a Samza container starts, let’s start the ZooKeeper, Kafka, and YARN.</p>
+
+<div class="highlight"><pre><code class="bash">bin/grid</code></pre></div>
+
+<p>If you get a complaint that JAVA_HOME is not set, then you’ll need to set it. This can be done on OSX by running:</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">export </span><span class="nv">JAVA_HOME</span><span class="o">=</span><span class="k">$(</span>/usr/libexec/java_home<span class="k">)</span></code></pre></div>
+
+<p>Once the grid starts, you can start the wikipedia-feed Samza job.</p>
+
+<div class="highlight"><pre><code class="bash">mvn clean package
+mkdir -p deploy/samza
+tar -xvf ./target/hello-samza-0.8.0-dist.tar.gz -C deploy/samza
+deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-feed.properties</code></pre></div>
+
+<p>When the wikipedia-feed job starts up, a single Samza container will be created to process all incoming messages. This is the container that we’ll want to connect to from the remote debugger.</p>
+
+<h3 id="connect-the-remote-debugger">Connect the Remote Debugger</h3>
+
+<p>Switch back to Eclipse, and set a break point in TaskInstance.process by clicking on a line inside TaskInstance.process, and clicking “Run” > “Toggle Breakpoint”. A blue circle should appear to the left of the line. This will let you see incoming messages as they arrive.</p>
+
+<p>Setup a remote debugging session: “Run” > “Debug Configurations…” > right click on “Remote Java Application” > “New”. Set the name to ‘wikipedia-feed-debug’. Set the port to 9009 (matching the port in the task.opts configuration). Click “Source” > “Add…” > “Java Project”. Select all of the Samza projects that you imported (i.e. samza-api, samza-core, etc). If you would like to set breakpoints in your own Stream task, also add the project that contains your StreamTask implementation. Click ‘Debug’.</p>
+
+<p>After a few moments, Eclipse should connect to the wikipedia-feed job, and ask you to switch to Debug mode. Once in debug, you’ll see that it’s broken at the TaskInstance.process method. From here, you can step through code, inspect variable values, etc.</p>
+
+<p>Congratulations, you’ve got a remote debug connection to your StreamTask!</p>

+<p>This tutorial is to help you run <a href="../../../startup/hello-samza/0.8/">Hello Samza</a> if you can not connect to the internet. </p>
+
+<h3 id="test-your-connection">Test Your Connection</h3>
+
+<p>Ping irc.wikimedia.org. Sometimes the firewall in your company blocks this service.</p>
+
+<div class="highlight"><pre><code class="bash">telnet irc.wikimedia.org 6667</code></pre></div>
+
+<p>You should see something like this:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">Trying 208.80.152.178...
+Connected to ekrem.wikimedia.org.
+Escape character is '^]'.
+NOTICE AUTH :*** Processing connection to irc.pmtpa.wikimedia.org
+NOTICE AUTH :*** Looking up your hostname...
+NOTICE AUTH :*** Checking Ident
+NOTICE AUTH :*** Found your hostname
+</code></pre></div>
+<p>Otherwise, you may have the connection problem.</p>
+
+<h3 id="use-local-data-to-run-hello-samza">Use Local Data to Run Hello Samza</h3>
+
+<p>We provide an alternative to get wikipedia feed data. Instead of running</p>
+
+<div class="highlight"><pre><code class="bash">deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-feed.properties</code></pre></div>
+
+<p>You will run</p>
+
+<div class="highlight"><pre><code class="bash">bin/produce-wikipedia-raw-data.sh</code></pre></div>
+
+<p>This script will read wikipedia feed data from local file and produce them to the Kafka broker. By default, it produces to localhost:9092 as the Kafka broker and uses localhost:2181 as zookeeper. You can overwrite them:</p>
+
+<div class="highlight"><pre><code class="bash">bin/produce-wikipedia-raw-data.sh -b yourKafkaBrokerAddress -z yourZookeeperAddress</code></pre></div>
+
+<p>Now you can go back to Generate Wikipedia Statistics section in <a href="../../../startup/hello-samza/0.8/">Hello Samza</a> and follow the remaining steps.</p>
+
+<h3 id="a-little-explanation">A Little Explanation</h3>
+
+<p>The goal of</p>

+
+<p>is to deploy a Samza job which listens to wikipedia API, receives the feed in realtime and produces the feed to the Kafka topic wikipedia-raw. The alternative in this tutorial is reading local wikipedia feed in an infinite loop and producing the data to Kafka wikipedia-raw. The follow-up job, wikipedia-parser is getting data from Kafka topic wikipedia-raw, so as long as we have correct data in Kafka topic wikipedia-raw, we are fine. All Samza jobs are connected by the Kafka and do not depend on each other.</p>

+-->
+
+<p>You must successfully run the <a href="../../../startup/hello-samza/0.8/">hello-samza</a> project in a single-node YARN by following the <a href="../../../startup/hello-samza/0.8/">hello-samza</a> tutorial. Now it’s time to run the Samza job in a “real” YARN grid (with more than one node).</p>
+
+<h2 id="set-up-multi-node-yarn">Set Up Multi-node YARN</h2>
+
+<p>If you already have a multi-node YARN cluster (such as CDH5 cluster), you can skip this set-up section.</p>
+
+<h3 id="basic-yarn-setting">Basic YARN Setting</h3>
+
+<p>1. Download <a href="http://mirror.symnds.com/software/Apache/hadoop/common/hadoop-2.4.0/hadoop-2.4.0.tar.gz">YARN 2.4</a> to /tmp and untar it.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd</span> /tmp
+tar -xvf hadoop-2.4.0.tar.gz
+<span class="nb">cd </span>hadoop-2.4.0</code></pre></div>
+
+<p>2. Set up environment variables.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">export </span><span class="nv">HADOOP_YARN_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>
+mkdir conf
+<span class="nb">export </span><span class="nv">HADOOP_CONF_DIR</span><span class="o">=</span><span class="nv">$HADOOP_YARN_HOME</span>/conf</code></pre></div>
+
+<p>3. Configure YARN setting file.</p>
+
+<div class="highlight"><pre><code class="bash">cp ./etc/hadoop/yarn-site.xml conf
+vi conf/yarn-site.xml</code></pre></div>
+
+<p>Add the following property to yarn-site.xml:</p>
+
+<div class="highlight"><pre><code class="xml"><span class="nt"><property></span>
+ <span class="nt"><name></span>yarn.resourcemanager.hostname<span class="nt"></name></span>
+ <span class="c"><!-- hostname that is accessible from all NMs --></span>
+ <span class="nt"><value></span>yourHostname<span class="nt"></value></span>
+<span class="nt"></property></span></code></pre></div>
+
+<p>Download and add capacity-schedule.xml.</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">curl http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-tests/src/test/resources/capacity-scheduler.xml?view=co > conf/capacity-scheduler.xml
+</code></pre></div>
+<h3 id="set-up-http-filesystem-for-yarn">Set Up Http Filesystem for YARN</h3>
+
+<p>The goal of these steps is to configure YARN to read http filesystem because we will use Http server to deploy Samza job package. If you want to use HDFS to deploy Samza job package, you can skip step 4~6 and follow <a href="deploy-samza-job-from-hdfs.html">Deploying a Samza Job from HDFS</a></p>
+
+<p>4. Download Scala package and untar it.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd</span> /tmp
+curl http://www.scala-lang.org/files/archive/scala-2.10.3.tgz > scala-2.10.3.tgz
+tar -xvf scala-2.10.3.tgz</code></pre></div>
+
+<p>5. Add Scala and its log jars.</p>
+
+<div class="highlight"><pre><code class="bash">cp /tmp/scala-2.10.3/lib/scala-compiler.jar <span class="nv">$HADOOP_YARN_HOME</span>/share/hadoop/hdfs/lib
+cp /tmp/scala-2.10.3/lib/scala-library.jar <span class="nv">$HADOOP_YARN_HOME</span>/share/hadoop/hdfs/lib
+curl http://search.maven.org/remotecontent?filepath<span class="o">=</span>org/clapper/grizzled-slf4j_2.10/1.0.1/grizzled-slf4j_2.10-1.0.1.jar > <span class="nv">$HADOOP_YARN_HOME</span>/share/hadoop/hdfs/lib/grizzled-slf4j_2.10-1.0.1.jar</code></pre></div>
+
+<p>6. Add http configuration in core-site.xml (create the core-site.xml file and add content).</p>
+
+<div class="highlight"><pre><code class="xml">vi $HADOOP_YARN_HOME/conf/core-site.xml</code></pre></div>
+
+<p>Add the following code:</p>
+
+<div class="highlight"><pre><code class="xml"><span class="cp"><?xml-stylesheet type="text/xsl" href="configuration.xsl"?></span>
+<span class="nt"><configuration></span>
+ <span class="nt"><property></span>
+ <span class="nt"><name></span>fs.http.impl<span class="nt"></name></span>
+ <span class="nt"><value></span>org.apache.samza.util.hadoop.HttpFileSystem<span class="nt"></value></span>
+ <span class="nt"></property></span>
+<span class="nt"></configuration></span></code></pre></div>
+
+<h3 id="distribute-hadoop-file-to-slaves">Distribute Hadoop File to Slaves</h3>
+
+<p>7. Basically, you copy the hadoop file in your host machine to slave machines. (172.21.100.35, in my case):</p>
+
+<div class="highlight"><pre><code class="bash">scp -r . 172.21.100.35:/tmp/hadoop-2.4.0
+<span class="nb">echo </span>172.21.100.35 > conf/slaves
+sbin/start-yarn.sh</code></pre></div>
+
+<ul>
+<li>If you get “172.21.100.35: Error: JAVA<em>HOME is not set and could not be found.”, you’ll need to add a conf/hadoop-env.sh file to the machine with the failure (172.21.100.35, in this case), which has “export JAVA</em>HOME=/export/apps/jdk/JDK-1<em>6</em>0<em>27” (or wherever your JAVA</em>HOME actually is).</li>
+</ul>
+
+<p>8. Validate that your nodes are up by visiting http://yourHostname:8088/cluster/nodes.</p>
+
+<h2 id="deploy-samza-job">Deploy Samza Job</h2>
+
+<p>Some of the following steps are exactlly identical to what you have seen in <a href="../../../startup/hello-samza/0.8/">hello-samza</a>. You may skip them if you have already done so.</p>
+
+<p>1. Download Samza and publish it to Maven local repository.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd</span> /tmp
+git clone http://git-wip-us.apache.org/repos/asf/incubator-samza.git
+<span class="nb">cd </span>incubator-samza
+./gradlew clean publishToMavenLocal
+<span class="nb">cd</span> ..</code></pre></div>
+
+<p>2. Download hello-samza project and change the job properties file.</p>
+
+<div class="highlight"><pre><code class="bash">git clone git://github.com/linkedin/hello-samza.git
+<span class="nb">cd </span>hello-samza
+vi src/main/config/wikipedia-feed.properties</code></pre></div>
+
+<p>Change the yarn.package.path property to be:</p>
+
+<div class="highlight"><pre><code class="jproperties"><span class="na">yarn.package.path</span><span class="o">=</span><span class="s">http://yourHostname:8000/target/hello-samza-0.8.0-dist.tar.gz</span></code></pre></div>
+
+<p>3. Complie hello-samza.</p>
+
+<div class="highlight"><pre><code class="bash">mvn clean package
+mkdir -p deploy/samza
+tar -xvf ./target/hello-samza-0.8.0-dist.tar.gz -C deploy/samza</code></pre></div>
+
+<p>4. Deploy Samza job package to Http server..</p>
+
+<p>Open a new terminal, and run:</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd</span> /tmp/hello-samza <span class="o">&&</span> python -m SimpleHTTPServer</code></pre></div>
+
+<p>Go back to the original terminal (not the one running the HTTP server):</p>
+
+<div class="highlight"><pre><code class="bash">deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-feed.properties</code></pre></div>
+
+<p>Go to http://yourHostname:8088 and find the wikipedia-feed job. Click on the ApplicationMaster link to see that it’s running.</p>
+
+<p>Congratulations! You now run the Samza job in a “real” YARN grid!</p>

+<p>Samza’s <a href="../../documentation/0.8/container/checkpointing.html">checkpointing</a> implementation changed between Samza 0.7.0 and 0.8.0. If you are running a Samza job with 0.7.0, and upgrade to 0.8.0, your job’s checkpoint offsets will be lost, and the job will start (by default) with the most recent message in its input streams. If this is undesirable, and a job needs to pick up where it left off, the following steps must be taken:</p>
+
+<ol>
+<li>Shutdown your job.</li>
+<li>Run the <a href="https://git-wip-us.apache.org/repos/asf?p=incubator-samza.git;a=blob;f=samza-kafka/src/main/scala/org/apache/samza/util/CheckpointMigrationTool.scala;h=5c4b3c4c544ae4367377b1a84d9a85a3de671018;hb=0.8.0">CheckpointMigrationTool</a>.</li>
+<li>Start your job.</li>
+</ol>
+
+<p>The CheckpointMigrationTool is responsible for migrating your checkpoint topic from the 0.7.0 style format to the 0.8.0 style format. This tool works only against Kafka, so you must be storing your checkpoints in Kafka with the <a href="https://git-wip-us.apache.org/repos/asf?p=incubator-samza.git;a=blob;f=samza-kafka/src/main/scala/org/apache/samza/checkpoint/kafka/KafkaCheckpointManager.scala;h=1d5627d0c561a0be6b48ee307b755958e62b783e;hb=0.8.0">KafkaCheckpointManager</a>.</p>
+
+<h3 id="running-checkpointmigrationtool">Running CheckpointMigrationTool</h3>
+
+<p>Checkout Samza 0.8.0:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">git clone http://git-wip-us.apache.org/repos/asf/incubator-samza.git
+cd incubator-samza
+git fetch origin 0.8.0
+git checkout 0.8.0
+</code></pre></div>
+<p>Run the checkpoint migration task:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">./gradlew samza-shell:checkpointMigrationTool -PconfigPath=file:///path/to/job/config.properties
+</code></pre></div>
+<p>The configPath property should be pointed at the .properties file for the job you wish to migrate. The tool will use the job’s properties file to connect to the Kafka cluster, and migrate the checkpointed offsets to the 0.8.0 format. Once the tool is complete, the job should be restarted so that it can pick up the migrated offsets.</p>
+
+<p><em>NOTE: The checkpointMigrationTool task must be run from a machine that can connect to the Kafka cluster.</em></p>

+
+<p>The <a href="https://github.com/apache/incubator-samza-hello-samza">hello-samza</a> project is a stand-alone project designed to help you run your first Samza job.</p>
+
+<h3 id="get-the-code">Get the Code</h3>
+
+<p>Check out the hello-samza project:</p>
+
+<div class="highlight"><pre><code class="bash">git clone git://git.apache.org/incubator-samza-hello-samza.git hello-samza
+<span class="nb">cd </span>hello-samza
+git checkout latest</code></pre></div>
+
+<p>This project contains everything you’ll need to run your first Samza jobs.</p>
+
+<h3 id="start-a-grid">Start a Grid</h3>
+
+<p>A Samza grid usually comprises three different systems: <a href="http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html">YARN</a>, <a href="http://kafka.apache.org/">Kafka</a>, and <a href="http://zookeeper.apache.org/">ZooKeeper</a>. The hello-samza project comes with a script called “grid” to help you setup these systems. Start by running:</p>
+
+<div class="highlight"><pre><code class="bash">bin/grid bootstrap</code></pre></div>
+
+<p>This command will download, install, and start ZooKeeper, Kafka, and YARN. It will also check out the latest version of Samza and build it. All package files will be put in a sub-directory called “deploy” inside hello-samza’s root folder.</p>
+
+<p>If you get a complaint that JAVA_HOME is not set, then you’ll need to set it to the path where Java is installed on your system.</p>
+
+<p>Once the grid command completes, you can verify that YARN is up and running by going to <a href="http://localhost:8088">http://localhost:8088</a>. This is the YARN UI.</p>
+
+<h3 id="build-a-samza-job-package">Build a Samza Job Package</h3>
+
+<p>Before you can run a Samza job, you need to build a package for it. This package is what YARN uses to deploy your jobs on the grid.</p>
+
+<div class="highlight"><pre><code class="bash">mvn clean package
+mkdir -p deploy/samza
+tar -xvf ./target/hello-samza-0.8.0-dist.tar.gz -C deploy/samza</code></pre></div>
+
+<h3 id="run-a-samza-job">Run a Samza Job</h3>
+
+<p>After you’ve built your Samza package, you can start a job on the grid using the run-job.sh script.</p>
+
+<div class="highlight"><pre><code class="bash">deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-feed.properties</code></pre></div>
+
+<p>The job will consume a feed of real-time edits from Wikipedia, and produce them to a Kafka topic called “wikipedia-raw”. Give the job a minute to startup, and then tail the Kafka topic:</p>
+
+<div class="highlight"><pre><code class="bash">deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-raw</code></pre></div>
+
+<p>Pretty neat, right? Now, check out the YARN UI again (<a href="http://localhost:8088">http://localhost:8088</a>). This time around, you’ll see your Samza job is running!</p>
+
+<p>If you can not see any output from Kafka consumer, you may have connection problem. Check <a href="../../../learn/tutorials/0.8/run-hello-samza-without-internet.html">here</a>.</p>
+
+<h3 id="generate-wikipedia-statistics">Generate Wikipedia Statistics</h3>
+
+<p>Let’s calculate some statistics based on the messages in the wikipedia-raw topic. Start two more jobs:</p>
+
+<div class="highlight"><pre><code class="bash">deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-parser.properties
+deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$PWD</span>/deploy/samza/config/wikipedia-stats.properties</code></pre></div>
+
+<p>The first job (wikipedia-parser) parses the messages in wikipedia-raw, and extracts information about the size of the edit, who made the change, etc. You can take a look at its output with:</p>
+
+<div class="highlight"><pre><code class="bash">deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-edits</code></pre></div>
+
+<p>The last job (wikipedia-stats) reads messages from the wikipedia-edits topic, and calculates counts, every ten seconds, for all edits that were made during that window. It outputs these counts to the wikipedia-stats topic.</p>
+
+<div class="highlight"><pre><code class="bash">deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-stats</code></pre></div>
+
+<p>The messages in the stats topic look like this:</p>
+
+<div class="highlight"><pre><code class="json"><span class="p">{</span><span class="nt">"is-talk"</span><span class="p">:</span><span class="mi">2</span><span class="p">,</span><span class="nt">"bytes-added"</span><span class="p">:</span><span class="mi">5276</span><span class="p">,</span><span class="nt">"edits"</span><span class="p">:</span><span class="mi">13</span><span class="p">,</span><span class="nt">"unique-titles"</span><span class="p">:</span><span class="mi">13</span><span class="p">}</span>

+
+<p>If you check the YARN UI, again, you’ll see that all three jobs are now listed.</p>
+
+<h3 id="shutdown">Shutdown</h3>
+
+<p>After you’re done, you can clean everything up using the same grid script.</p>
+
+<div class="highlight"><pre><code class="bash">bin/grid stop all</code></pre></div>
+
+<p>Congratulations! You’ve now setup a local grid that includes YARN, Kafka, and ZooKeeper, and run a Samza job on it.
