+
+<body>
+<h2>Data Model</h2>
+<p>
+    This processor executes an Apache Flume sink. FlowFiles are wrapped in 
Flume's
+    Event interface. The content of the FlowFile becomes the body of the Event 
and
+    the attributes of the FlowFile become Event headers. The following special
+    headers are also set:
+</p>
+<table id="headers">
+    <tr>
+        <th>Flume Event Header</th>
+        <th>FlowFile Attribute</th>
+    </tr>
+    <tr>
+        <td>nifi.entry.date</td>
+        <td>FlowFile#getEntryDate()</td>
+    </tr>
+    <tr>
+        <td>nifi.id</td>
+        <td>FlowFile#getId()</td>
+    </tr>
+    <tr>
+        <td>nifi.last.queue.date</td>
+        <td>FlowFile#getLastQueueDate()</td>
+    </tr>
+    <tr>
+        <td>nifi.lineage.start.date</td>
+        <td>FlowFile#getLineageStartDate()</td>
+    </tr>
+    <tr>
+        <td>nifi.size</td>
+        <td>FlowFile#getSize()</td>
+    </tr>
+</table>
+<h2>Warning</h2>
+<p>
+    In NiFi, the contents of a FlowFile are accessed via a stream, but in 
Flume it is
+    stored in a byte array. This means the full content will be loaded into 
memory when
+    a FlowFile is processed by the ExecuteFlumeSink processor. You should 
consider the
+    typical size of the FlowFiles you'll process and the batch size, if any, 
your sink
+    is configured with when setting NiFi's heap size.
+</p>
+<h2>Configuration Details</h2>
+<p>
+    This processor is designed to execute arbitrary Flume sinks. Most of the 
details
+    of configuring the sink is deferred to Flume's built-in configuration 
system.
+    For details on the available settings for each sink type, refer to the 
Flume
+    <a href="http://flume.apache.org/FlumeUserGuide.html#flume-sinks";>User 
Guide</a>.
+    Configuring the Flume sink is a four step process:
+</p>
+<ol>
+    <li>Set the Sink Type property to a valid Flume sink type.</li>
+    <li>
+        Set the Agent Name property to the name of the agent in your
+        Flume configuration. This is the prefix of the properties in the Flume
+        configuration file. Example: <code>tier1</code>
+    </li>
+    <li>
+        Set the Sink Name property to the name of the sink in your Flume
+        configuration. If Agent Name is <code>tier1</code>, then the Sink Name
+        is the value of the <code>tier1.sinks</code> property. Example: 
<code>sink-1</code>
+    </li>
+    <li>
+        Copy and paste the configuration for the sink from your Flume 
configuration
+        file into the Flume Configuration property. Assuming you're using
+        the same Agent Name and Sink Name as in the examples above, this will 
be all
+        of the properties that start with <code>tier1.sinks.sink-1</code>.
+        Do not copy the <code>tier1.sinks.sink-1.type</code> or
+        <code>tier1.sinks.sink-1.channel</code> properties.
+    </li>
+</ol>
+<h2>Usage Example</h2>
+<p>
+    Assuming you had the following existing Flume configuration file:
+</p>
+    <pre>
+a1.sources = r1
+a1.sinks = k1
+a1.channels = c1
+
+a1.sources.r1.type = netcat
+a1.sources.r1.bind = localhost
+a1.sources.r1.port = 44444
+
+a1.sinks.k1.type = hdfs
+a1.sinks.k1.channel = c1
+a1.sinks.k1.hdfs.path = /flume/events/%y-%m-%d/%H%M/%S
+a1.sinks.k1.hdfs.filePrefix = events-
+a1.sinks.k1.hdfs.round = true
+a1.sinks.k1.hdfs.roundValue = 10
+a1.sinks.k1.hdfs.roundUnit = minute
+
+a1.channels.c1.type = memory
+a1.channels.c1.capacity = 1000
+a1.channels.c1.transactionCapacity = 100
+
+a1.sources.r1.channels = c1
+a1.sinks.k1.channel = c1</pre>
+<p>
+    Then you'd configure the ExecuteFlumeSink as follows:
+</p>
+<table id="example">
+    <tr>
+        <th>Property</th>
+        <th>Value</th>
+    </tr>
+    <tr>
+        <td>Sink Type</td>
+        <td>hdfs</td>
+    </tr>
+    <tr>
+        <td>Agent Name</td>
+        <td>a1</td>
+    </tr>
+    <tr>
+        <td>Sink Name</td>
+        <td>k1</td>
+    </tr>
+    <tr>
+        <td>Flume Configuration</td>
+        <td>
+            <code>
+                a1.sinks.k1.hdfs.path = /flume/events/%y-%m-%d/%H%M/%S<br>
+                a1.sinks.k1.hdfs.filePrefix = events-<br>
+                a1.sinks.k1.hdfs.round = true<br>
+                a1.sinks.k1.hdfs.roundValue = 10<br>
+                a1.sinks.k1.hdfs.roundUnit = minute
+            </code>
+        </td>
+    </tr>
+</table>
+</body>
+</html>

+<b>Example:</b> if you defined property <code>`SQL.mydb`</code> and linked it 
to any DBCPService, 
+then you can access it from code <code>SQL.mydb.rows('select * from 
mytable')</code><br/>
+
+<br/>The processor automatically takes connection from dbcp service before 
executing script and tries to handle transaction:
+<br/> database transactions automatically rolled back on script exception and 
committed on success.
+<br/>Or you can manage transaction manually.
+<br/>NOTE: Script must not disconnect connection.

+<h2>SessionFile - flow file extension</h2>
+<p>
+  The (org.apache.nifi.processors.groovyx.flow.SessionFile) is an actual 
object returned by session in Extended Groovy processor.<br/>
+  This flow file is a container that references session and the real flow 
file.<br/>
+  This allows to use simplified syntax to work with file attributes and 
content:
+</p>
+<p><i>set new attribute value</i></p>
+<pre>
+  flowFile.ATTRIBUTE_NAME = ATTRIBUTE_VALUE 
+  flowFile.'mime.type' = 'text/xml' 
+  flowFile.putAttribute("ATTRIBUTE_NAME", ATTRIBUTE_VALUE)
+  //the same as
+  flowFile = session.putAttribute(flowFile, "ATTRIBUTE_NAME", ATTRIBUTE_VALUE)
+</pre>
+  
+<p><i>remove attribute</i></p>
+<pre>
+  flowFile.ATTRIBUTE_NAME = null
+  //equals to
+  flowFile = session.removeAttribute(flowFile, "ATTRIBUTE_NAME")
+</pre>
+
+<p><i>get attribute value</i></p>
+<pre>
+  String a = flowFile.ATTRIBUTE_NAME
+</pre>
+  
+<p><i>write content</i></p>
+<pre>
+  flowFile.write("UTF-8", "THE CharSequence to write into flow file replacing 
current content")
+  flowFile.write("UTF-8"){writer-> 
+    do something with java.io.Writer...
+  }
+  flowFile.write{outStream-> 
+    do something with output stream...
+  }
+  flowFile.write{inStream, outStream-> 
+    do something with input and output streams... 
+  }
+</pre>
+
+<p><i>get content</i></p>
+<pre>
+  InputStream i = flowFile.read()
+  def json = new groovy.json.JsonSlurper().parse( flowFile.read() )
+  String text = flowFile.read().getText("UTF-8")
+</pre>
+  
+<p><i>transfer flow file to success relation</i></p>
+<pre>
+  REL_SUCCESS << flowFile 
+  flowFile.transfer(REL_SUCCESS)
+  //the same as:
+  session.transfer(flowFile, REL_SUCCESS)
+</pre>
+
+<p><i>work with dbcp</i></p>
+<pre>
+  import groovy.sql.Sql
+
+  //define property named `SQL.db` connected to a DBCPConnectionPool 
controller service
+  //for this case it's an H2 database example
+  
+  //read value from the database with prepared statement 
+  //and assign into flowfile attribute `db.yesterday`
+  def daysAdd = -1
+  def row = SQL.db.firstRow("select dateadd('DAY', ${daysAdd}, sysdate) as 
DB_DATE from dual")
+  flowFile.'db.yesterday' = row.DB_DATE
+
+  //to work with BLOBs and CLOBs in the database 
+  //use parameter casting using groovy.sql.Sql.BLOB(Stream) and 
groovy.sql.Sql.CLOB(Reader)
+  
+  //write content of the flow file into database blob
+  flowFile.read{ rawIn->
+    def parms = [
+      p_id   : flowFile.ID as Long, //get flow file attribute named `ID`
+      p_data : Sql.BLOB( rawIn ),   //use input stream as BLOB sql parameter
+    ]
+    SQL.db.executeUpdate(parms, "update mytable set data = :p_data where id = 
:p_id")
+  }
+</pre>
+
+
+<h2>Handling processor start &amp; stop</h2>
+
+<p>In the extended groovy processor you can catch `start` and `stop` events by 
providing corresponding static methods:</p>
+<pre>
+  import org.apache.nifi.processor.ProcessContext
+  import java.util.concurrent.atomic.AtomicLong
+
+  class Const{
+    static Date startTime = null;
+    static AtomicLong triggerCount = null;
+  }
+
+  static onStart(ProcessContext context){
+    Const.startTime = new Date()
+    Const.triggerCount = new AtomicLong(0)
+    println "onStart $context ${Const.startTime}"
+  }
+
+  static onStop(ProcessContext context){
+    def alive = (System.currentTimeMillis() - Const.startTime.getTime()) / 1000
+    println "onStop $context executed ${ Const.triggerCount } times during ${ 
alive } seconds"
+  }
+
+
+  flowFile.'trigger.count' = Const.triggerCount.incrementAndGet()
+  REL_SUCCESS << flowFile
+</pre>
+<br/>
+<br/>
+<br/>
+<br/>
+</body>
+</html>

================================================== -->
+        <h2>Description:</h2>
+        <p>This processor is used to create a Hadoop Sequence File, which 
essentially is a file of key/value pairs. The key 
+            will be a file name and the value will be the flow file content. 
The processor will take either a merged (a.k.a. packaged) flow 
+            file or a singular flow file. Historically, this processor handled 
the merging by type and size or time prior to creating a 
+            SequenceFile output; it no longer does this. If creating a 
SequenceFile that contains multiple files of the same type is desired,
+            precede this processor with a <code>RouteOnAttribute</code> 
processor to segregate files of the same type and follow that with a
+            <code>MergeContent</code> processor to bundle up files. If the 
type of files is not important, just use the 
+            <code>MergeContent</code> processor. When using the 
<code>MergeContent</code> processor, the following Merge Formats are 
+            supported by this processor:
+        <ul>
+            <li>TAR</li>
+            <li>ZIP</li>
+            <li>FlowFileStream v3</li>
+        </ul>
+        The created SequenceFile is named the same as the incoming FlowFile 
with the suffix '.sf'. For incoming FlowFiles that are 
+        bundled, the keys in the SequenceFile are the individual file names, 
the values are the contents of each file.
+    </p>
+    NOTE: The value portion of a key/value pair is loaded into memory. While 
there is a max size limit of 2GB, this could cause memory
+    issues if there are too many concurrent tasks and the flow file sizes are 
large.
