+
+<p>YARN is Hadoop’s next-generation cluster manager. It allows developers to deploy and execute arbitrary commands on a grid. If you’re unfamiliar with YARN, or the concept of an ApplicationMaster (AM), please read Hadoop’s <a href="http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html">YARN</a> page.</p>
+
+<h3 id="integration">Integration</h3>
+
+<p>Samza’s main integration with YARN comes in the form of a Samza ApplicationMaster. This is the chunk of code responsible for managing a Samza job in a YARN grid. It decides what to do when a stream processor fails, which machines a Samza job’s <a href="../container/samza-container.html">containers</a> should run on, and so on.</p>
+
+<p>When the Samza ApplicationMaster starts up, it does the following:</p>
+
+<ol>
+<li>Receives configuration from YARN via the STREAMING_CONFIG environment variable.</li>
+<li>Starts a JMX server on a random port.</li>
+<li>Instantiates a metrics registry and reporters to keep track of relevant metrics.</li>
+<li>Registers the AM with YARN’s RM.</li>
+<li>Get the total number of partitions for the Samza job using each input stream’s PartitionManager (see the <a href="../container/streams.html">Streams</a> page for details).</li>
+<li>Read the total number of containers requested from the Samza job’s configuration.</li>
+<li>Assign each partition to a container (called a Task Group in Samza’s AM dashboard).</li>
+<li>Make a <a href="http://hadoop.apache.org/docs/current/api/org/apache/hadoop/yarn/api/records/ResourceRequest.html">ResourceRequest</a> to YARN for each container.</li>
+<li>Poll the YARN RM every second to check for allocated and released containers.</li>
+</ol>
+
+<p>From this point on, the ApplicationMaster just reacts to events from the RM.</p>
+
+<h3 id="fault-tolerance">Fault Tolerance</h3>
+
+<p>Whenever a container is allocated, the AM will work with the YARN NM to start a SamzaContainer (with appropriate partitions assigned to it) in the container. If a container fails with a non-zero return code, the AM will request a new container, and restart the SamzaContainer. If a SamzaContainer fails too many times, too quickly, the ApplicationMaster will fail the whole Samza job with a non-zero return code. See the yarn.container.retry.count and yarn.container.retry.window.ms <a href="../jobs/configuration.html">configuration</a> parameters for details.</p>
+
+<p>When the AM receives a reboot signal from YARN, it will throw a SamzaException. This will trigger a clean and successful shutdown of the AM (YARN won’t think the AM failed).</p>
+
+<p>If the AM, itself, fails, YARN will handle restarting the AM. When the AM is restarted, all containers that were running will be killed, and the AM will start from scratch. The same list of operations, shown above, will be executed. The AM will request new containers for its SamzaContainers, and proceed as though it has just started for the first time. YARN has a yarn.resourcemanager.am.max-retries configuration parameter that’s defined in <a href="http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-common/yarn-default.xml">yarn-site.xml</a>. This configuration defaults to 1, which means that, by default, a single AM failure will cause your Samza job to stop running.</p>
+
+<h3 id="dashboard">Dashboard</h3>
+
+<p>Samza’s ApplicationMaster comes with a dashboard to show useful information such as:</p>
+
+<ol>
+<li>Where containers are located.</li>
+<li>Links to logs.</li>
+<li>The Samza job’s configuration.</li>
+<li>Container failure count.</li>
+</ol>
+
+<p>You can find this dashboard by going to your YARN grid’s ResourceManager page (usually something like <a href="http://localhost:8088/cluster">http://localhost:8088/cluster</a>), and clicking on the “ApplicationMaster” link of a running Samza job.</p>
+
+<p><img src="/img/latest/learn/documentation/yarn/samza-am-dashboard.png" alt="Screenshot of ApplicationMaster dashboard" class="diagram-large"></p>
+
+<h3 id="security">Security</h3>
+
+<p>The Samza dashboard’s HTTP access is currently un-secured, even when using YARN in secure-mode. This means that users with access to a YARN grid could port-scan a Samza ApplicationMaster’s HTTP server, and open the dashboard in a browser to view its contents. Sensitive configuration can be viewed by anyone, in this way, and care should be taken. There are plans to secure Samza’s ApplicationMaster using <a href="http://docs.hortonworks.com/HDPDocuments/HDP1/HDP-1.3.0/bk_installing_manually_book/content/rpm-chap14-2-3-1.html">Hadoop’s security</a> features (<a href="http://en.wikipedia.org/wiki/SPNEGO">SPENAGO</a>).</p>
+
+<p>See Samza’s <a href="../operations/security.html">security</a> page for more details.</p>

+
+<p>When running Samza jobs in a shared, distributed environment, the stream processors can have an impact on one another’s performance. A stream processor that uses 100% of a machine’s CPU will slow down all other stream processors on the machine.</p>
+
+<p>One of <a href="http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html">YARN</a>’s responsibilities is to manage resources so that this doesn’t happen. Each of YARN’s Node Managers (NM) has a chunk of “resources” dedicated to it. The YARN Resource Manager (RM) will only allow a container to be allocated on a NM if it has enough resources to satisfy the container’s needs.</p>
+
+<p>YARN currently supports resource management for memory and CPU.</p>
+
+<h3 id="memory">Memory</h3>
+
+<p>YARN will automatically enforce memory limits for all containers that it executes. All containers must have a max-memory size defined when they’re created. If the sum of all memory usage for processes associated with a single YARN container exceeds this maximum, YARN will kill the container.</p>
+
+<p>Samza supports memory limits using the yarn.container.memory.mb and yarn.am.container.memory.mb configuration parameters. Keep in mind that this is simply the amount of memory YARN will allow a <a href="../container/samza-container.html">SamzaContainer</a> or <a href="application-master.html">ApplicationMaster</a> to have. You’ll still need to configure your heap settings appropriately using task.opts, when using Java (the default is -Xmx160M). See the <a href="../jobs/configuration.html">Configuration</a> and <a href="../jobs/packaging.html">Packaging</a> pages for details.</p>
+
+<h3 id="cpu">CPU</h3>
+
+<p>YARN has the concept of a virtual core. Each NM is assigned a total number of virtual cores (32, by default). When a container request is made, it must specify how many virtual cores it needs. The YARN RM will only assign the container to a NM that has enough virtual cores to satisfy the request.</p>
+
+<h4 id="cgroups">CGroups</h4>
+
+<p>Unlike memory, which YARN can enforce itself (by looking at the /proc folder), YARN can’t enforce CPU isolation, since this must be done at the Linux kernel level. One of YARN’s interesting new features is its support for Linux <a href="https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt">CGroups</a>. CGroups are a way to control process utilization at the kernel level in Linux.</p>
+
+<p>If YARN is setup to use CGroups, then YARN will guarantee that a container will get at least the amount of CPU that it requires. Currently, YARN will give you more CPU, if it’s available. For details on enforcing “at most” CPU usage, see <a href="https://issues.apache.org/jira/browse/YARN-810">YARN-810</a>. </p>
+
+<p>See <a href="http://riccomini.name/posts/hadoop/2013-06-14-yarn-with-cgroups/">this blog post</a> for details on setting up YARN with CGroups.</p>

+
+<p>This tutorial uses <a href="../../../startup/hello-samza/latest/">hello-samza</a> to illustrate how to run a Samza job if you want to publish the Samza job’s .tar.gz package to HDFS.</p>
+
+<h3 id="upload-the-package">Upload the package</h3>
+
+<div class="highlight"><pre><code class="bash">hadoop fs -put ./samza-job-package/target/samza-job-package-0.7.0-dist.tar.gz /path/for/tgz</code></pre></div>
+
+<h3 id="add-hdfs-configuration">Add HDFS configuration</h3>
+
+<p>Put the hdfs-site.xml file of your cluster into ~/.samza/conf directory (The same place as the yarn-site.xml). If you set HADOOP_CONF_DIR, put the hdfs-site.xml in your configuration directory if the hdfs-site.xml is not there.</p>
+
+<h3 id="change-properties-file">Change properties file</h3>
+
+<p>Change the yarn.package.path in the properties file to your HDFS location.</p>
+
+<div class="highlight"><pre><code class="jproperties"><span class="na">yarn.package.path</span><span class="o">=</span><span class="s">hdfs://<hdfs name node ip>:<hdfs name node port>/path/to/tgz</span></code></pre></div>
+
+<p>Then you should be able to run the Samza job as described in <a href="../../../startup/hello-samza/latest/">hello-samza</a>.</p>

+
+<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/latest/">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 ./samza-job-package/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/latest/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">$(</span>/usr/libexec/java_home<span class="k">)</span></code></pre></div>
+
+<p>Once the grid starts, you can start the wikipedia-feed Samza job.</p>
+
+<div class="highlight"><pre><code class="bash">mvn clean package
+mkdir -p deploy/samza
+tar -xvf ./samza-job-package/target/samza-job-package-0.7.0-dist.tar.gz -C deploy/samza
+deploy/samza/bin/run-job.sh --config-factory<span class="o">=</span>org.apache.samza.config.factories.PropertiesConfigFactory --config-path<span class="o">=</span>file://<span class="nv">$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/latest/">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>

+
+<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/latest/">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/latest/">hello-samza</a> project in a single-node YARN by following the <a href="../../../startup/hello-samza/latest/">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. Dowload <a href="http://mirror.symnds.com/software/Apache/hadoop/common/hadoop-2.3.0/hadoop-2.3.0.tar.gz">YARN 2.3</a> to /tmp and untar it.</p>
+
+<div class="highlight"><pre><code class="bash"><span class="nb">cd</span> /tmp
+tar -xvf hadoop-2.3.0.tar.gz
+<span class="nb">cd </span>hadoop-2.3.0</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-2.3.0
+<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/latest/">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 samza-job-package/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/samza-job-package/target/samza-job-package-0.7.0-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 ./samza-job-package/target/samza-job-package-0.7.0-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>
+
