+<h2>Enabling Alluxio Interpreter</h2>
+
+<p>In a notebook, to enable the <strong>Alluxio</strong> interpreter, click on the <strong>Gear</strong> icon and select <strong>Alluxio</strong>.</p>
+
+<h2>Using the Alluxio Interpreter</h2>
+
+<p>In a paragraph, use <code>%alluxio</code> to select the <strong>Alluxio</strong> interpreter and then input all commands.</p>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>%alluxio

+<h2>How to test it&#39;s working</h2>
+
+<p>Be sure to have configured correctly the Alluxio interpreter, then open a new paragraph and type one of the above commands.</p>
+
+<p>Below a simple example to show how to interact with Alluxio interpreter.
+Following steps are performed:</p>
+
+<ul>
+<li>using sh interpreter a new text file is created on local machine</li>
+<li>using Alluxio interpreter:
+
+<ul>
+<li>is listed the content of the afs (Alluxio File System) root</li>
+<li>the file previously created is copied to afs</li>
+<li>is listed again the content of the afs root to check the existence of the new copied file</li>
+<li>is showed the content of the copied file (using the tail command)</li>
+<li>the file previously copied to afs is copied to local machine</li>
+</ul></li>
+<li> using sh interpreter it&#39;s checked the existence of the new file copied from Alluxio and its content is showed</li>
+</ul>

+<h1>Beam interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="http://beam.incubator.apache.org">Apache Beam</a> is an open source unified platform for data processing pipelines. A pipeline can be build using one of the Beam SDKs.
+The execution of the pipeline is done by different Runners. Currently, Beam supports Apache Flink Runner, Apache Spark Runner, and Google Dataflow Runner.</p>
+
+<h2>How to use</h2>
+
+<p>Basically, you can write normal Beam java code where you can determine the Runner. You should write the main method inside a class becuase the interpreter invoke this main to execute the pipeline. Unlike Zeppelin normal pattern, each paragraph is considered as a separate job, there isn&#39;t any relation to any other paragraph.</p>
+
+<p>The following is a demonstration of a word count example with data represented in array of strings
+But it can read data from files by replacing <code>Create.of(SENTENCES).withCoder(StringUtf8Coder.of())</code> with <code>TextIO.Read.from(&quot;path/to/filename.txt&quot;)</code></p>

+<h1>BigQuery Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://cloud.google.com/bigquery/what-is-bigquery">BigQuery</a> is a highly scalable no-ops data warehouse in the Google Cloud Platform. Querying massive datasets can be time consuming and expensive without the right hardware and infrastructure. Google BigQuery solves this problem by enabling super-fast SQL queries against append-only tables using the processing power of Google&#39;s infrastructure. Simply move your data into BigQuery and let us handle the hard work. You can control access to both the project and your data based on your business needs, such as giving others the ability to view or query your data.  </p>
+
+<h2>Configuration</h2>
+
+<table class="table-configuration">
+  <tr>
+    <th>Name</th>
+    <th>Default Value</th>
+    <th>Description</th>
+  </tr>
+  <tr>
+    <td>zeppelin.bigquery.project_id</td>
+    <td>  </td>
+    <td>Google Project Id</td>
+  </tr>
+  <tr>
+    <td>zeppelin.bigquery.wait_time</td>
+    <td>5000</td>
+    <td>Query Timeout in Milliseconds</td>

+    <td>Max result set size</td>
+  </tr>
+  <tr>
+    <td>zeppelin.bigquery.sql_dialect</td>
+    <td></td>
+    <td>BigQuery SQL dialect (standardSQL or legacySQL). If empty, [query prefix](https://cloud.google.com/bigquery/docs/reference/standard-sql/enabling-standard-sql#sql-prefix) like '#standardSQL' can be used.</td>
+  </tr>
+</table>
+
+<h2>BigQuery API</h2>
+
+<p>Zeppelin is built against BigQuery API version v2-rev265-1.21.0 - <a href="https://developers.google.com/resources/api-libraries/documentation/bigquery/v2/java/latest/">API Javadocs</a></p>
+
+<h2>Enabling the BigQuery Interpreter</h2>
+
+<p>In a notebook, to enable the <strong>BigQuery</strong> interpreter, click the <strong>Gear</strong> icon and select <strong>bigquery</strong>.</p>
+
+<h3>Provide Application Default Credentials</h3>
+
+<p>Within Google Cloud Platform (e.g. Google App Engine, Google Compute Engine),
+built-in credentials are used by default.</p>
+
+<p>Outside of GCP, follow the Google API authentication instructions for <a href="https://zeppelin.apache.org/docs/latest/storage/storage.html#notebook-storage-in-gcs">Zeppelin Google Cloud Storage</a></p>
+
+<h2>Using the BigQuery Interpreter</h2>
+
+<p>In a paragraph, use <code>%bigquery.sql</code> to select the <strong>BigQuery</strong> interpreter and then input SQL statements against your datasets stored in BigQuery.
+You can use <a href="https://cloud.google.com/bigquery/query-reference">BigQuery SQL Reference</a> to build your own SQL.</p>
+
+<p>For Example, SQL to query for top 10 departure delays across airports using the flights public dataset</p>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>%bigquery.sql
+SELECT departure_airport,count<span class="o">(</span><span class="k">case</span> when departure_delay&gt;0 <span class="k">then</span> <span class="m">1</span> <span class="k">else</span> <span class="m">0</span> end<span class="o">)</span> as no_of_delays 
+FROM <span class="o">[</span>bigquery-samples:airline_ontime_data.flights<span class="o">]</span> 
+group by departure_airport 
+order by <span class="m">2</span> desc 
+limit <span class="m">10</span>
+</code></pre></div>
+<p>Another Example, SQL to query for most commonly used java packages from the github data hosted in BigQuery </p>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>%bigquery.sql
+SELECT
+  package,
+  COUNT<span class="o">(</span>*<span class="o">)</span> count
+FROM <span class="o">(</span>
+  SELECT
+    REGEXP_EXTRACT<span class="o">(</span>line, r<span class="s1">&#39; ([a-z0-9\._]*)\.&#39;</span><span class="o">)</span> package,
+    id
+  FROM <span class="o">(</span>
+    SELECT
+      SPLIT<span class="o">(</span>content, <span class="s1">&#39;\n&#39;</span><span class="o">)</span> line,
+      id
+    FROM
+      <span class="o">[</span>bigquery-public-data:github_repos.sample_contents<span class="o">]</span>
+    WHERE
+      content CONTAINS <span class="s1">&#39;import&#39;</span>
+      AND sample_path LIKE <span class="s1">&#39;%.java&#39;</span>
+    HAVING
+      LEFT<span class="o">(</span>line, <span class="m">6</span><span class="o">)=</span><span class="s1">&#39;import&#39;</span> <span class="o">)</span>
+  GROUP BY
+    package,
+    id <span class="o">)</span>
+GROUP BY
+  <span class="m">1</span>
+ORDER BY
+  count DESC
+LIMIT
+  <span class="m">40</span>
+</code></pre></div>
