+
+<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>
+
+<h2>Configuration</h2>

+<blockquote>
+<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>
+</blockquote>
+
+<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="bash language-bash" data-lang="bash">%elasticsearch
+<span class="nb">help</span>
+
+Elasticsearch interpreter:
+General format: <<span class="nb">command</span>> /<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 class="o">)</span>
+ - types: list of document types separated by commas <span class="o">(</span>depends on the <span class="nb">command</span><span class="o">)</span>
+Commands:
+ - search /indices/types <query>
+ . indices and types can be omitted <span class="o">(</span>at least, you have to provide <span class="s1">'/'</span><span class="o">)</span>
+ . a query is either a JSON-formatted query, nor a lucene query
+ - size <value>
+ . defines the size of the result <span class="nb">set</span> <span class="o">(</span>default value is in the config<span class="o">)</span>
+ . <span class="k">if </span>used, this <span class="nb">command </span>must be declared before a search <span class="nb">command</span>
+ - count /indices/types <query>
+ . same comments as <span class="k">for </span>the search
+ - get /index/type/id
+ - delete /index/type/id
+ - index /index/type/id <json-formatted document>
+ . the id can be omitted, elasticsearch will generate one
+</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="bash language-bash" data-lang="bash">%elasticsearch
+get /index/type/id
+</code></pre></div>
+<p>Example:
+<img src="/docs/0.9.0/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>

+<p>A search query can also contain <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations.html">aggregations</a>.

+

+
+<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="text language-text" data-lang="text">{
+ "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/0.9.0/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/0.9.0/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/0.9.0/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/0.9.0/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/0.9.0/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/0.9.0/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:
+<img src="/docs/0.9.0/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="bash language-bash" data-lang="bash">%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/0.9.0/assets/themes/zeppelin/img/docs-img/elasticsearch-count.png" alt="Elasticsearch - Count"></p></li>
+<li><p>With a query:
+<img src="/docs/0.9.0/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="bash language-bash" data-lang="bash">%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="bash language-bash" data-lang="bash">%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="bash language-bash" data-lang="bash">%elasticsearch
+size <span class="k">${</span><span class="nv">limit</span><span class="p">=10</span><span class="k">}</span>
+search /index/type <span class="o">{</span> <span class="s2">"query"</span>: <span class="o">{</span> <span class="s2">"match_all"</span>: <span class="o">{</span> <span class="o">}</span> <span class="o">}</span> <span class="o">}</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>
+
+<p>In Zeppelin 0.9, we refactor the Flink interpreter in Zeppelin to support the latest version of Flink. <strong>Only Flink 1.10+ is supported, old version of flink won't work.</strong>
+Apache Flink is supported in Zeppelin with Flink interpreter group which consists of below five interpreters.</p>

+
+<h2>StreamExecutionEnvironment, ExecutionEnvironment, StreamTableEnvironment, BatchTableEnvironment</h2>
+
+<p>Zeppelin will create 6 variables as flink scala (<code>%flink</code>) entry point:</p>
+
+<ul>
+<li><code>senv</code> (StreamExecutionEnvironment), </li>
+<li><code>benv</code> (ExecutionEnvironment)</li>
+<li><code>stenv</code> (StreamTableEnvironment for blink planner) </li>
+<li><code>btenv</code> (BatchTableEnvironment for blink planner)</li>
+<li><code>stenv_2</code> (StreamTableEnvironment for flink planner) </li>
+<li><code>btenv_2</code> (BatchTableEnvironment for flink planner)</li>
+</ul>
+
+<p>And will create 6 variables as pyflink (<code>%flink.pyflink</code> or <code>%flink.ipyflink</code>) entry point:</p>
+
+<ul>
+<li><code>s_env</code> (StreamExecutionEnvironment), </li>
+<li><code>b_env</code> (ExecutionEnvironment)</li>
+<li><code>st_env</code> (StreamTableEnvironment for blink planner) </li>
+<li><code>bt_env</code> (BatchTableEnvironment for blink planner)</li>
+<li><code>st_env_2</code> (StreamTableEnvironment for flink planner) </li>
+<li><code>bt_env_2</code> (BatchTableEnvironment for flink planner)</li>
+</ul>
+
+<h2>Blink/Flink Planner</h2>
+
+<p>There're 2 planners supported by Flink's table api: <code>flink</code> & <code>blink</code>.</p>
+
+<ul>
+<li>If you want to use DataSet api, and convert it to flink table then please use flink planner (<code>btenv_2</code> and <code>stenv_2</code>).</li>
+<li>In other cases, we would always recommend you to use <code>blink</code> planner. This is also what flink batch/streaming sql interpreter use (<code>%flink.bsql</code> & <code>%flink.ssql</code>)</li>
+</ul>
+
+<p>Check this <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/table/common.html#main-differences-between-the-two-planners">page</a> for the difference between flink planner and blink planner.</p>
+
+<h2>Execution mode (Local/Remote/Yarn)</h2>
+
+<p>Flink in Zeppelin supports 3 execution modes (<code>flink.execution.mode</code>):</p>
+
+<ul>
+<li>Local</li>
+<li>Remote</li>
+<li>Yarn</li>
+</ul>
+
+<h3>Run Flink in Local Mode</h3>
+
+<p>Running Flink in Local mode will start a MiniCluster in local JVM. By default, the local MiniCluster will use port 8081, so make sure this port is available in your machine,
+otherwise you can configure <code>rest.port</code> to specify another port. You can also specify <code>local.number-taskmanager</code> and <code>flink.tm.slot</code> to customize the number of TM and number of slots per TM,
+because by default it is only 4 TM with 1 Slots which may not be enough for some cases.</p>
+
+<h3>Run Flink in Remote Mode</h3>
+
+<p>Running Flink in remote mode will connect to a existing flink cluster which could be standalone cluster or yarn session cluster. Besides specifying <code>flink.execution.mode</code> to be <code>remote</code>. You also need to specify
+<code>flink.execution.remote.host</code> and <code>flink.execution.remote.port</code> to point to flink job manager.</p>
+
+<h3>Run Flink in Yarn Mode</h3>
+
+<p>In order to run flink in Yarn mode, you need to make the following settings:</p>
+
+<ul>
+<li>Set <code>flink.execution.mode</code> to <code>yarn</code></li>
+<li>Set <code>HADOOP_CONF_DIR</code> in flink's interpreter setting.</li>
+<li>Make sure <code>hadoop</code> command is on your PATH. Because internally flink will call command <code>hadoop classpath</code> and load all the hadoop related jars in the flink interpreter process</li>
+</ul>
+
+<h2>How to use Hive</h2>
+
+<p>In order to use Hive in Flink, you have to make the following setting.</p>
+
+<ul>
+<li>Set <code>zeppelin.flink.enableHive</code> to be true</li>
+<li>Set <code>zeppelin.flink.hive.version</code> to be the hive version you are using.</li>
+<li>Set <code>HIVE_CONF_DIR</code> to be the location where <code>hive-site.xml</code> is located. Make sure hive metastore is started and you have configured <code>hive.metastore.uris</code> in <code>hive-site.xml</code></li>
+<li>Copy the following dependencies to the lib folder of flink installation.Â
+
+<ul>
+<li>flink-connector-hive_2.11â1.10.0.jar</li>
+<li>flink-hadoop-compatibility_2.11â1.10.0.jar</li>
+<li>hive-exec-2.x.jar (for hive 1.x, you need to copy hive-exec-1.x.jar, hive-metastore-1.x.jar, libfb303â0.9.2.jar and libthrift-0.9.2.jar)</li>
+</ul></li>
+</ul>
+
+<h2>Flink Batch SQL</h2>
+
+<p><code>%flink.bsql</code> is used for flink's batch sql. You can type <code>help</code> to get all the available commands.
+It supports all the flink sql, including DML/DDL/DQL.</p>
+
+<ul>
+<li>Use <code>insert into</code> statement for batch ETL</li>
+<li>Use <code>select</code> statement for batch data analytics </li>
+</ul>
+
+<h2>Flink Streaming SQL</h2>
+
+<p><code>%flink.ssql</code> is used for flink's streaming sql. You just type <code>help</code> to get all the available commands.
+It supports all the flink sql, including DML/DDL/DQL.</p>
+
+<ul>
+<li>Use <code>insert into</code> statement for streaming ETL</li>
+<li>Use <code>select</code> statement for streaming data analytics</li>
+</ul>
+
+<h2>Streaming Data Visualization</h2>
+
+<p>Zeppelin supports 3 types of streaming data analytics:
+* Single
+* Update
+* Append</p>
+
+<h3>type=single</h3>
+
+<p>Single mode is for the case when the result of sql statement is always one row, such as the following example. The output format is HTML,
+and you can specify paragraph local property <code>template</code> for the final output content template.
+And you can use <code>{i}</code> as placeholder for the ith column of result.</p>
+
+<p><center>
+ <img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_single_mode.gif" alt="Interactive Help">
+ </center></p>
+
+<h3>type=update</h3>
+
+<p>Update mode is suitable for the case when the output is more than one rows, and always will be updated continuously.
+Hereâs one example where we use group by.</p>
+
+<p><center>
+ <img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_update_mode.gif" alt="Interactive Help">
+ </center></p>
+
+<h3>type=append</h3>
+
+<p>Append mode is suitable for the scenario where output data is always appended. E.g. the following example which use tumble window.</p>
+
+<p><center>
+ <img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_append_mode.gif" alt="Interactive Help">
+ </center></p>
+
+<h2>Flink UDF</h2>
+
+<p>You can use Flink scala UDF or Python UDF in sql. UDF for batch and streaming sql is the same. Here're 2 examples.</p>
+
+<ul>
+<li>Scala UDF</li>
+</ul>
+<div class="highlight"><pre><code class="scala language-scala" data-lang="scala"><span class="o">%</span><span class="n">flink</span>

+</code></pre></div>
+<p>Zeppelin only supports scala and python for flink interpreter, if you want to write java udf or the udf is pretty complicated which make it not suitable to write in Zeppelin,
+then you can write the udf in IDE and build a udf jar.
+In Zeppelin you just need to specify <code>flink.udf.jars</code> to this jar, and flink
+interpreter will detect all the udfs in this jar and register all the udfs to TableEnvironment, the udf name is the class name.</p>
+
+<h2>PyFlink(%flink.pyflink)</h2>
+
+<p>In order to use PyFlink in Zeppelin, you just need to do the following configuration.
+* Install apache-flink (e.g. pip install apache-flink)
+* Set <code>zeppelin.pyflink.python</code> to the python executable where apache-flink is installed in case you have multiple python installed.
+* Copy flink-python_2.11â1.10.0.jar from flink opt folder to flink lib folder</p>
+
+<p>And PyFlink will create 6 variables for you:</p>
+
+<ul>
+<li><code>s_env</code> (StreamExecutionEnvironment), </li>
+<li><code>b_env</code> (ExecutionEnvironment)</li>
+<li><code>st_env</code> (StreamTableEnvironment for blink planner) </li>
+<li><code>bt_env</code> (BatchTableEnvironment for blink planner)</li>
+<li><code>st_env_2</code> (StreamTableEnvironment for flink planner) </li>
+<li><code>bt_env_2</code> (BatchTableEnvironment for flink planner)</li>
+</ul>
+
+<h3>IPython Support(%flink.ipyflink)</h3>
+
+<p>By default, zeppelin would use IPython in <code>%flink.pyflink</code> when IPython is available, Otherwise it would fall back to the original python implementation.
+For the IPython features, you can refer doc<a href="python.html">Python Interpreter</a></p>
+
+<h2>ZeppelinContext</h2>
+
+<p>Zeppelin automatically injects <code>ZeppelinContext</code> as variable <code>z</code> in your Scala/Python environment. <code>ZeppelinContext</code> provides some additional functions and utilities.
+See <a href="../usage/other_features/zeppelin_context.html">Zeppelin-Context</a> for more details. You can use <code>z</code> to display both flink DataSet and batch/stream table.</p>
+
+<ul>
+<li><p>Display DataSet
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_z_dataset.png" alt="Interactive Help">
+</center></p></li>
+<li><p>Display Batch Table
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_z_batch_table.png" alt="Interactive Help">

+<li><p>Display Stream Table
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/flink_z_stream_table.gif" alt="Interactive Help">
+</center></p></li>
+</ul>
+
+<h2>Paragraph local properties</h2>
+
+<p>In the section of <code>Streaming Data Visualization</code>, we demonstrate the different visualization type via paragraph local properties: <code>type</code>.
+In this section, we will list and explain all the supported local properties in flink interpreter.</p>
+
