+<h1>Zeppelin Tutorial</h1>
+
+<div id="toc"></div>
+
+<p>This tutorial walks you through some of the fundamental Zeppelin concepts.
We will assume you have already installed Zeppelin. If not, please see <a
href="../install/install.html">here</a> first.</p>
+
+<p>Current main backend processing engine of Zeppelin is <a
href="https://spark.apache.org";>Apache Spark</a>. If you're new to this
system, you might want to start by getting an idea of how it processes data to
get the most out of Zeppelin.</p>
+
+<h2>Tutorial with Local File</h2>
+
+<h3>Data Refine</h3>
+
+<p>Before you start Zeppelin tutorial, you will need to download <a
href="http://archive.ics.uci.edu/ml/machine-learning-databases/00222/bank.zip";>bank.zip</a>.
</p>
+
+<p>First, to transform csv format data into RDD of <code>Bank</code> objects,
run following script. This will also remove header using <code>filter</code>
function.</p>
+<div class="highlight"><pre><code class="scala language-scala"

+<h3>Data Retrieval</h3>
+
+<p>Suppose we want to see age distribution from <code>bank</code>. To do this,
run:</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="k">sql</span> <span
class="k">select</span> <span class="n">age</span><span class="p">,</span>

<span class="k">order</span> <span class="k">by</span> <span
class="n">age</span>
+</code></pre></div>
+<p>You can make input box for setting age condition by replacing
<code>30</code> with <code>${maxAge=30}</code>.</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="k">sql</span> <span

<span class="n">age</span> <span class="k">order</span> <span
class="k">by</span> <span class="n">age</span>
+</code></pre></div>
+<p>Now we want to see age distribution with certain marital status and add
combo box to select marital status. Run:</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="k">sql</span> <span
class="k">select</span> <span class="n">age</span><span class="p">,</span>

+</code></pre></div>

+
+<h2>Tutorial with Streaming Data</h2>
+
+<h3>Data Refine</h3>
+
+<p>Since this tutorial is based on Twitter's sample tweet stream, you must
configure authentication with a Twitter account. To do this, take a look at <a
href="https://databricks-training.s3.amazonaws.com/realtime-processing-with-spark-streaming.html#twitter-credential-setup";>Twitter
Credential Setup</a>. After you get API keys, you should fill out credential
related values(<code>apiKey</code>, <code>apiSecret</code>,
<code>accessToken</code>, <code>accessTokenSecret</code>) with your API keys on
following script.</p>
+
+<p>This will create a RDD of <code>Tweet</code> objects and register these
stream data as a table:</p>

+<h3>Data Retrieval</h3>
+
+<p>For each following script, every time you click run button you will see
different result since it is based on real-time data.</p>
+
+<p>Let's begin by extracting maximum 10 tweets which contain the word
<strong>girl</strong>.</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="k">sql</span> <span
class="k">select</span> <span class="o">*</span> <span class="k">from</span>
<span class="n">tweets</span> <span class="k">where</span> <span
class="nb">text</span> <span class="k">like</span> <span
class="s1">'%girl%'</span> <span class="k">limit</span> <span
class="mi">10</span>
+</code></pre></div>
+<p>This time suppose we want to see how many tweets have been created per sec
during last 60 sec. To do this, run:</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="k">sql</span> <span
class="k">select</span> <span class="n">createdAt</span><span

<span class="n">createdAt</span> <span class="k">order</span> <span
class="k">by</span> <span class="n">createdAt</span>
+</code></pre></div>
+<p>You can make user-defined function and use it in Spark SQL. Let's try
it by making function named <code>sentiment</code>. This function will return
one of the three attitudes( positive, negative, neutral ) towards the
parameter.</p>

+<h1>Apache Zeppelin Configuration REST API</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p>Apache Zeppelin provides several REST APIs for interaction and remote
activation of zeppelin functionality.
+All REST APIs are available starting with the following endpoint
<code>http://[zeppelin-server]:[zeppelin-port]/api</code>.
+Note that Apache Zeppelin REST APIs receive or return JSON objects, it is
recommended for you to install some JSON viewers such as <a
href="https://chrome.google.com/webstore/detail/jsonview/chklaanhfefbnpoihckbnefhakgolnmc";>JSONView</a>.</p>
+
+<p>If you work with Apache Zeppelin and find a need for an additional REST
API, please <a href="http://zeppelin.apache.org/community.html";>file an issue
or send us an email</a>.
+nd a need for an additional REST API, please <a
href="../../community.html">file an issue or send us mail</a>.</p>
