+<p>S4 ships with a toolkit for creating, packaging, deploying and running applications.</p>
+
+<p>From the source distribution, these tools are built by running:</p>
+
+<pre><code>gradlew s4-tools:installApp
+</code></pre>
+
+<p>This compiles the s4-tools subproject and generates shell scripts.</p>
+
+<h1 id="available-commands">Available commands</h1>
+
+<p>Here is the list of commands available with the <code>s4</code> tool. For each of these commands, the comprehensive documentation of all parameters is shown by specifying the <code>-help</code> option.</p>
+
+<p>Syntax: <code>s4 <command> <options></code></p>
+
+<table>
+<thead><tr>

+ <th>Command</th>
+ </tr></thead>

+<tr>
+<td>Get information about S4 infrastructure</td>
+ <td>Shows status of S4 clusters, apps, nodes and external streams</td>
+ <td><code>status</code></td>
+ </tr>
+</tbody>
+</table>
+<p>In addition, for easy injection of data, the <code>adapter</code> command allows to start an node without having to package and deploy the application.</p>
+
+<h1 id="undeploying-an-application">Undeploying an application</h1>
+
+<p>There is currently no specific command for undeploying S4 applications. The recomended way for removing an application deployed on cluster C1 is to:</p>
+
+<ul>
+<li>kill S4 nodes belonging to cluster C1</li>
+ <li>delete ZooKeeper subtree /s4/clusters/C1</li>
+ <li>redefine cluster C1</li>
+ <li>deploy new application</li>
+ <li>restart nodes for cluster C1 (this could be automated with some utility like <a href="http://cr.yp.to/daemontools.html">daemontools</a>)</li>

+</blockquote>
+
+<h1 id="twitter-trending-example">Twitter trending example</h1>
+
+<p>Letâs have a look at another application, that computes trendy Twitter topics by listening to the spritzer stream from the Twitter API. This application was adapted from a previous example in S4 0.3.</p>
+
+<h2 id="overview">Overview</h2>
+
+<p>This application is divided into:</p>
+
+<ul>
+<li>twitter-counter , in test-apps/twitter-counter/ : extracts topics from tweets and maintains a count of the most popular ones, periodically dumped to disk</li>
+ <li>twitter-adapter, in test-apps/twitter-adapter/ : listens to the feed from Twitter, converts status text into S4 events, and passes them to the âRawStatusâ stream</li>
+</ul>
+<p>Have a look at the code in these directories. Youâll note that:</p>
+
+<ul>
+<li>the build.gradle file must be tailored to include new dependencies (twitter4j libs in twitter-adapter)</li>
+ <li>events are partitioned through various keys</li>
+</ul>
+<h2 id="run-it">Run it!</h2>
+
+<blockquote>
+ <p>Note: You need a twitter4j.properties file in your home directory with the following content (debug is optional):</p>
+</blockquote>
+
+<pre><code>debug=true
+user=<a twitter username>
+password=<matching password>
+</code></pre>
+
+<ul>
+<li>
+ <p>Start a Zookeeper instance. From the S4 base directory, do:</p>
+
+ <pre><code> ./s4 zkServer
+</code></pre>
+ </li>
+ <li>
+ <p>Define 2 clusters : 1 for deploying the twitter-counter app, and 1 for the adapter app</p>
+
+ <pre><code> ./s4 newCluster -c=cluster1 -nbTasks=2 -flp=12000; ./s4 newCluster -c=cluster2 -nbTasks=1 -flp=13000
+</code></pre>
+ </li>
+ <li>
+ <p>Start 2 app nodes (you may want to start each node in a separate console) :</p>
+
+ <pre><code> ./s4 node -c=cluster1
+ ./s4 node -c=cluster1
+</code></pre>
+ </li>
+ <li>
+ <p>Start 1 node for the adapter app:</p>
+
+ <pre><code> ./s4 node -c=cluster2 -p=s4.adapter.output.stream=RawStatus
+</code></pre>
+ </li>
+ <li>
+ <p>Deploy twitter-counter app (you may also first build the s4r then publish it, as described in the previous section)</p>
+
+ <pre><code> ./s4 deploy -appName=twitter-counter -c=cluster1 -b=`pwd`/test-apps/twitter-counter/build.gradle
+</code></pre>
+ </li>
+ <li>
+ <p>Deploy twitter-adapter app. In this example, we donât directly specify the app class of the adapter, we use the deployment approach for apps (remember, the adapter is also an app).</p>
+
+ <pre><code> ./s4 deploy -appName=twitter-adapter -c=cluster2 -b=`pwd`/test-apps/twitter-adapter/build.gradle
+</code></pre>
+ </li>
+ <li>
+ <p>Observe the current 10 most popular topics in file TopNTopics.txt. The file gets updated at regular intervals, and only outputs topics with a minimum of 10 occurrences, so you may have to wait a little before the file is updated :</p>
+
+ <pre><code> tail -f TopNTopics.txt
+</code></pre>
+ </li>
+ <li>
+ <p>You may also check the status of the S4 node with:</p>
+
+ <pre><code> ./s4 status
+</code></pre>
+ </li>
+</ul>
+<hr>
+<h1 id="what-next">What next?</h1>
+
+<p>You have now seen some basics applications, and you know how to run them, and how to get events into the system. You may now try to code your own apps with your own data.</p>
+
+<p><a href="../application_dependencies">This page</a> will help for specifying your own dependencies.</p>
+
+<p>There are more parameters available for the scripts (typing the name of the task will list the options). In particular, if you want distributed deployments, youâll need to pass the Zookeeper connection strings when you start the nodes.</p>
+
+<p>You may also customize the communication and the core layers of S4 by tweaking configuration files and modules.</p>
+
+<p>Last, the <a href="http://people.apache.org/~mmorel/apache-s4-0.6.0-incubating-doc/javadoc/">javadoc</a> will help you when writing applications.</p>
+
+<p>We hope this will help you start rapidly, and remember: weâre happy to help!</p>

- <li>
- <p>Define 2 clusters : 1 for deploying the twitter-counter app, and 1 for the adapter app</p>
-
- <pre><code> ./s4 newCluster -c=cluster1 -nbTasks=2 -flp=12000; ./s4 newCluster -c=cluster2 -nbTasks=1 -flp=13000
-</code></pre>
- </li>
- <li>
- <p>Start 2 app nodes (you may want to start each node in a separate console) :</p>
-
- <pre><code> ./s4 node -c=cluster1
- ./s4 node -c=cluster1
-</code></pre>
- </li>
- <li>
- <p>Start 1 node for the adapter app:</p>
-
- <pre><code> ./s4 node -c=cluster2 -p=s4.adapter.output.stream=RawStatus
-</code></pre>
- </li>
- <li>
- <p>Deploy twitter-counter app (you may also first build the s4r then publish it, as described in the previous section)</p>
-
- <pre><code> ./s4 deploy -appName=twitter-counter -c=cluster1 -b=`pwd`/test-apps/twitter-counter/build.gradle
-</code></pre>
- </li>
- <li>
- <p>Deploy twitter-adapter app. In this example, we donât directly specify the app class of the adapter, we use the deployment approach for apps (remember, the adapter is also an app).</p>
-
- <pre><code> ./s4 deploy -appName=twitter-adapter -c=cluster2 -b=`pwd`/test-apps/twitter-adapter/build.gradle
-</code></pre>
- </li>
- <li>
- <p>Observe the current 10 most popular topics in file TopNTopics.txt. The file gets updated at regular intervals, and only outputs topics with a minimum of 10 occurrences, so you may have to wait a little before the file is updated :</p>
-
- <pre><code> tail -f TopNTopics.txt
-</code></pre>
- </li>
- <li>
- <p>You may also check the status of the S4 node with:</p>
-
- <pre><code> ./s4 status
-</code></pre>
- </li>
-</ul>
-<hr>
<h1 id="what-next">What next?</h1>
-<p>You have now seen some basics applications, and you know how to run them, and how to get events into the system. You may now try to code your own apps with your own data.</p>
-
-<p><a href="../application_dependencies">This page</a> will help for specifying your own dependencies.</p>
-
-<p>There are more parameters available for the scripts (typing the name of the task will list the options). In particular, if you want distributed deployments, youâll need to pass the Zookeeper connection strings when you start the nodes.</p>
-
-<p>You may also customize the communication and the core layers of S4 by tweaking configuration files and modules.</p>
-
-<p>Last, the <a href="http://people.apache.org/~mmorel/apache-s4-0.6.0-incubating-doc/javadoc/">javadoc</a> will help you when writing applications.</p>
-
-<p>We hope this will help you start rapidly, and remember: weâre happy to help!</p>
+<p>We suggest you take a look at a more comprehensive <a href="../twitter_trending_example">example application</a>.</p>
