+
+<h2>Overview</h2>
+
+<p><a href="https://www.elastic.co/products/elasticsearch";>Elasticsearch</a>
is a highly scalable open-source full-text search and analytics engine.
+It allows you to store, search, and analyze big volumes of data quickly and in
near real time.
+It is generally used as the underlying engine/technology that powers
applications that have complex search features and requirements.</p>

+<p><strong>Note #1 :</strong> You can add more properties to configure the
Elasticsearch client.</p>
+
+<p><strong>Note #2 :</strong> If you use Shield, you can add a property named
<code>shield.user</code> with a value containing the name and the password (
format: <code>username:password</code> ). For more details about Shield
configuration, consult the <a
href="https://www.elastic.co/guide/en/shield/current/_using_elasticsearch_java_clients_with_shield.html";>Shield
reference guide</a>. Do not forget, to copy the shield client jar in the
interpreter directory
(<code>ZEPPELIN_HOME/interpreters/elasticsearch</code>).</p>

+
+<h2>Enabling the Elasticsearch Interpreter</h2>
+
+<p>In a notebook, to enable the <strong>Elasticsearch</strong> interpreter,
click the <strong>Gear</strong> icon and select
<strong>Elasticsearch</strong>.</p>
+
+<h2>Using the Elasticsearch Interpreter</h2>
+
+<p>In a paragraph, use <code>%elasticsearch</code> to select the Elasticsearch
interpreter and then input all commands.
+To get the list of available commands, use <code>help</code>.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+<span class="nb">help</span>
+
+Elasticsearch interpreter:
+General format: <command> /<indices>/<types>/<id>
<option> <JSON>
+ - indices: list of indices separated by commas <span
class="o">(</span>depends on the <span class="nb">command</span><span

+</code></pre></div>
+<blockquote>
+<p><strong>Tip :</strong> Use ( Ctrl + . ) for autocompletion.</p>
+</blockquote>
+
+<h3>Get</h3>
+
+<p>With the <code>get</code> command, you can find a document by id. The
result is a JSON document.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+get /index/type/id
+</code></pre></div>
+<p>Example:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-get.png"
alt="Elasticsearch - Get"></p>
+
+<h3>Search</h3>
+
+<p>With the <code>search</code> command, you can send a search query to
Elasticsearch. There are two formats of query:</p>
+
+<ul>
+<li>You can provide a JSON-formatted query, that is exactly what you provide
when you use the REST API of Elasticsearch.<br>
+
+<ul>
+<li>See <a
href="https://www.elastic.co/guide/en/elasticsearch/reference/current/search.html";>Elasticsearch
search API reference document</a> for more details about the content of the
search queries.</li>
+</ul></li>
+<li>You can also provide the content of a <code>query_string</code>.
+
+<ul>
+<li>This is a shortcut to a query like that: <code>{ "query": {
"query_string": { "query": "__HERE YOUR QUERY__",
"analyze_wildcard": true } } }</code></li>
+<li>See <a
href="https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax";>Elasticsearch
query string syntax</a> for more details about the content of such a
query.</li>
+</ul></li>
+</ul>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+search /index1,index2,.../type1,type2,... <JSON document containing the
query or query_string elements>
+</code></pre></div>
+<p>If you want to modify the size of the result set, you can add a line that
is setting the size, before your search command.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+size <span class="m">50</span>
+search /index1,index2,.../type1,type2,... <JSON document containing the
query or query_string elements>
+</code></pre></div>
+<blockquote>
+<p>A search query can also contain <a

+If there is at least one aggregation, the result of the first aggregation is
shown, otherwise, you get the search hits.</p>
+</blockquote>
+
+<p>Examples:</p>
+

+<blockquote>
+<p><strong>Important</strong> : a document in Elasticsearch is a JSON
document, so it is hierarchical, not flat as a row in a SQL table.
+For the Elastic interpreter, the result of a search query is flattened.</p>
+</blockquote>
+
+<p>Suppose we have a JSON document:</p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>{
+ "date": "2015-12-08T21:03:13.588Z",
+ "request": {
+ "method": "GET",
+ "url":
"/zeppelin/4cd001cd-c517-4fa9-b8e5-a06b8f4056c4",
+ "headers": [ "Accept: *.*", "Host:
apache.org"]
+ },
+ "status": "403",
+ "content_length": 1234
+}
+</code></pre></div>
+<p>The data will be flattened like this:</p>
+
+<table><thead>
+<tr>
+<th>content_length</th>
+<th>date</th>
+<th>request.headers[0]</th>
+<th>request.headers[1]</th>
+<th>request.method</th>
+<th>request.url</th>
+<th>status</th>
+</tr>
+</thead><tbody>
+<tr>
+<td>1234</td>
+<td>2015-12-08T21:03:13.588Z</td>
+<td>Accept: *.*</td>
+<td>Host: apache.org</td>
+<td>GET</td>
+<td>/zeppelin/4cd001cd-c517-4fa9-b8e5-a06b8f4056c4</td>
+<td>403</td>
+</tr>
+</tbody></table>
+
+<p>Examples:</p>
+
+<ul>
+<li><p>With a table containing the results:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-search-table.png"
alt="Elasticsearch - Search - table"></p></li>
+<li><p>You can also use a predefined diagram:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-search-pie.png"
alt="Elasticsearch - Search - diagram"></p></li>
+<li><p>With a JSON query:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-search-json-query-table.png"
alt="Elasticsearch - Search with query"></p></li>
+<li><p>With a JSON query containing a <code>fields</code> parameter (for
filtering the fields in the response): in this case, all the fields values in
the response are arrays, so, after flattening the result, the format of all the
field names is <code>field_name[x]</code>
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-query-with-fields-param.png"
alt="Elasticsearch - Search with query and a fields param"></p></li>
+<li><p>With a query string:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-query-string.png"
alt="Elasticsearch - Search with query string"></p></li>
+<li><p>With a query containing a multi-value metric aggregation:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-agg-multi-value-metric.png"
alt="Elasticsearch - Search with aggregation (multi-value metric)"></p></li>
+<li><p>With a query containing a multi-bucket aggregation:

src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-agg-multi-bucket-pie.png"
alt="Elasticsearch - Search with aggregation (multi-bucket)"></p></li>
+</ul>
+
+<h3>Count</h3>
+
+<p>With the <code>count</code> command, you can count documents available in
some indices and types. You can also provide a query.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+count /index1,index2,.../type1,type2,... <JSON document containing the
query OR a query string>
+</code></pre></div>
+<p>Examples:</p>
+
+<ul>
+<li><p>Without query:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-count.png"
alt="Elasticsearch - Count"></p></li>
+<li><p>With a query:
+<img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/elasticsearch-count-with-query.png"
alt="Elasticsearch - Count with query"></p></li>
+</ul>
+
+<h3>Index</h3>
+
+<p>With the <code>index</code> command, you can insert/update a document in
Elasticsearch.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+index /index/type/id <JSON document>
+
+%elasticsearch
+index /index/type <JSON document>
+</code></pre></div>
+<h3>Delete</h3>
+
+<p>With the <code>delete</code> command, you can delete a document.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+delete /index/type/id
+</code></pre></div>
+<h3>Apply Zeppelin Dynamic Forms</h3>
+
+<p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin
Dynamic Form</a> inside your queries. You can use both the <code>text
input</code> and <code>select form</code> parameterization features.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%elasticsearch
+size <span class="si">${</span><span class="nv">limit</span><span
class="p">=10</span><span class="si">}</span>
+search /index/type <span class="o">{</span> <span

+<h1>Flink interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://flink.apache.org";>Apache Flink</a> is an open source
platform for distributed stream and batch data processing. Flinkâs core is a
streaming dataflow engine that provides data distribution, communication, and
fault tolerance for distributed computations over data streams. Flink also
builds batch processing on top of the streaming engine, overlaying native
iteration support, managed memory, and program optimization.</p>
+
+<h2>How to start local Flink cluster, to test the interpreter</h2>
+
+<p>Zeppelin comes with pre-configured flink-local interpreter, which starts
Flink in a local mode on your machine, so you do not need to install
anything.</p>
+
+<h2>How to configure interpreter to point to Flink cluster</h2>
+
+<p>At the "Interpreters" menu, you have to create a new Flink
interpreter and provide next properties:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>property</th>
+ <th>value</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>host</td>
+ <td>local</td>
+ <td>host name of running JobManager. 'local' runs flink in local mode
(default)</td>
+ </tr>
+ <tr>
+ <td>port</td>
+ <td>6123</td>
+ <td>port of running JobManager</td>
+ </tr>
+</table>
+
+<p>For more information about Flink configuration, you can find it <a
href="https://ci.apache.org/projects/flink/flink-docs-release-1.0/setup/config.html";>here</a>.</p>
+
+<h2>How to test it's working</h2>
+
+<p>You can find an example of Flink usage in the Zeppelin Tutorial folder or
try the following word count example, by using the <a
href="https://www.zeppelinhub.com/viewer/notebooks/aHR0cHM6Ly9yYXcuZ2l0aHVidXNlcmNvbnRlbnQuY29tL05GTGFicy96ZXBwZWxpbi1ub3RlYm9va3MvbWFzdGVyL25vdGVib29rcy8yQVFFREs1UEMvbm90ZS5qc29u";>Zeppelin

+
+<p>This <a href="https://www.youtube.com/watch?v=zvzzA9GXu3Q";>Video
Tutorial</a> illustrates some of the features provided by the <code>Geode
Interpreter</code>.</p>
+
+<h2>Create Interpreter</h2>
+
+<p>By default Zeppelin creates one <code>Geode/OQL</code> instance. You can
remove it or create more instances.</p>
+
+<p>Multiple Geode instances can be created, each configured to the same or
different backend Geode cluster.
+But over time a <code>Notebook</code> can have only one Geode interpreter
instance <code>bound</code>.
+That means you <em>cannot</em> connect to different Geode clusters in the same
<code>Notebook</code>.
+This is a known Zeppelin limitation.</p>
+
+<p>To create new Geode instance open the <code>Interpreter</code> section and
click the <code>+Create</code> button.
+Pick a <code>Name</code> of your choice and from the <code>Interpreter</code>
drop-down select <code>geode</code>.<br>
+Then follow the configuration instructions and <code>Save</code> the new
instance.</p>
+
+<blockquote>
+<p>Note: The <code>Name</code> of the instance is used only to distinguish the
instances while binding them to the <code>Notebook</code>. The
<code>Name</code> is irrelevant inside the <code>Notebook</code>. In the
<code>Notebook</code> you must use <code>%geode.oql</code> tag.</p>
+</blockquote>
+
+<h2>Bind to Notebook</h2>
+
+<p>In the <code>Notebook</code> click on the <code>settings</code> icon in the
top right corner.
+The select/deselect the interpreters to be bound with the
<code>Notebook</code>.</p>
+
+<h2>Configuration</h2>
+
+<p>You can modify the configuration of the Geode from the
<code>Interpreter</code> section.
+The Geode interpreter expresses the following properties:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Property Name</th>
+ <th>Description</th>
+ <th>Default Value</th>
+ </tr>
+ <tr>
+ <td>geode.locator.host</td>
+ <td>The Geode Locator Host</td>
+ <td>localhost</td>
+ </tr>
+ <tr>
+ <td>geode.locator.port</td>
+ <td>The Geode Locator Port</td>
+ <td>10334</td>
+ </tr>
+ <tr>
+ <td>geode.max.result</td>
+ <td>Max number of OQL result to display to prevent the browser
overload</td>
+ <td>1000</td>
+ </tr>
+</table>
+
+<h2>How to use</h2>
+
+<blockquote>
+<p><em>Tip 1: Use (CTRL + .) for OQL auto-completion.</em></p>
+
+<p><em>Tip 2: Always start the paragraphs with the full
<code>%geode.oql</code> prefix tag! The short notation: <code>%geode</code>
would still be able run the OQL queries but the syntax highlighting and the
auto-completions will be disabled.</em></p>
+</blockquote>
+
+<h3>Create / Destroy Regions</h3>
+
+<p>The OQL specification does not support <a
href="https://cwiki.apache.org/confluence/display/GEODE/Index#Index-MainConceptsandComponents";>Geode
Regions</a> mutation operations.
+To <code>create</code>/<code>destroy</code> regions one should use the <a
href="http://geode-docs.cfapps.io/docs/tools_modules/gfsh/chapter_overview.html";>GFSH</a>
shell tool instead.
+In the following it is assumed that the GFSH is colocated with Zeppelin
server.</p>

+</code></pre></div>
+<p>Above snippet re-creates two regions: <code>regionEmployee</code> and
<code>regionCompany</code>.
+Note that you have to explicitly specify the locator host and port.
+The values should match those you have used in the Geode Interpreter
configuration.

href="https://issues.apache.org/jira/browse/ZEPPELIN-212";>2</a>].</p>
+</blockquote>
+
+<h3>GFSH Commands From The Shell</h3>
+
+<p>Use the Shell Interpreter (<code>%sh</code>) to run OQL commands form the
command line:</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>%sh
+<span class="nb">source</span> /etc/geode/conf/geode-env.sh
+gfsh -e <span class="s2">"connect"</span> -e <span
class="s2">"list members"</span>
+</code></pre></div>
+<h3>Apply Zeppelin Dynamic Forms</h3>
+
+<p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin
Dynamic Form</a> inside your OQL queries. You can use both the <code>text
input</code> and <code>select form</code> parameterization features</p>
+<div class="highlight"><pre><code class="language-sql"
data-lang="sql"><span></span><span class="o">%</span><span
class="n">geode</span><span class="p">.</span><span class="n">oql</span>

class="err">${</span><span class="n">Id</span><span class="err">}</span>
+</code></pre></div>
+<h3>Auto-completion</h3>
+
+<p>The Geode Interpreter provides a basic auto-completion functionality. On
<code>(Ctrl+.)</code> it list the most relevant suggestions in a pop-up
window.</p>
