+
+<p>Livy provides a programmatic Java/Scala and Python API that allows applications to run code inside
+Spark without having to maintain a local Spark context. Here shows how to use the Java API.</p>
+
+<p>Add the Livy client dependency to your application’s POM:</p>
+
+<div class="language-xml highlighter-rouge"><pre class="highlight"><code><span class="nt"><dependency></span>
+ <span class="nt"><groupId></span>org.apache.livy<span class="nt"></groupId></span>
+ <span class="nt"><artifactId></span>livy-client-http<span class="nt"></artifactId></span>
+ <span class="nt"><version></span>0.4.0-incubating<span class="nt"></version></span>
+<span class="nt"></dependency></span>
+</code></pre>
+</div>
+
+<p>Note: Until Livy’s first Apache release you will have to
+install the livy artifacts locally using <code class="highlighter-rouge">mvn install</code>.</p>
+
+<p>To be able to compile code that uses Spark APIs, also add the correspondent Spark dependencies.</p>
+
+<p>To run Spark jobs within your applications, extend <code class="highlighter-rouge">org.apache.livy.Job</code> and implement
+the functionality you need. Here’s an example job that calculates an approximate value for Pi:</p>
