+ <h2>Description:</h2>
+ <p>
+ This ControllerService serves as a general factory service to serving vendor specific
+ instances of the <i>javax.jms.ConnectionFactory</i>. It does so by allowing user to
+ configure vendor specific properties as well as point to the location of the vendor
+ provided JMS client libraries so the correct implementation of the <i>javax.jms.ConnectionFactory</i>
+ can be found, loaded, instantiated and served to the dependent Processors (see PublishJMS, ConsumeJMS).
+ </p>
+ <p>
+ To accommodate variety of JMS vendors and their implementation of the <i>ConnectionFactory</i>
+ this ControllerService exposes only 3 static configuration properties that are common across many implementations
+ of the <i>ConnectionFactory</i>. The rest of the configuration properties are set following
+ <a href="http://docstore.mik.ua/orelly/java-ent/jnut/ch06_02.htm">Java Beans</a> convention (see below).
+ </p>
+ <p>
+ The 3 static configuration properties are:
+ <ul>
+ <li><b>MQ ConnectionFactory Implementation</b> - A fully qualified name of the JMS ConnectionFactory implementation
+ class (i.e., org.apache.activemq.ActiveMQConnectionFactory)</li>
+ <li><b>MQ Client Libraries path</b> - Path to the directory with additional resources (i.e., JARs, configuration files etc.) to be added
+ to the classpath. Such resources typically represent target MQ client libraries for the ConnectionFactory
+ implementation. It is optional if you are using Apache ActiveMQ since its libraries are distributed with this component.</li>
+ <li><b>Broker URI</b> - URI pointing to the network location of the JMS Message broker. For example, 'tcp://myhost:61616' for ActiveMQ or simply 'myhost:1414'.</li>
+ </ul>
+ The rest of the properties are set as Dynamic Properties following <a href="http://docstore.mik.ua/orelly/java-ent/jnut/ch06_02.htm">Java Beans</a>
+ convention where a property name is derived from the <i>set*</i> method of the vendor specific ConnectionFactory's implementation.
+ For example, <i>com.ibm.mq.jms.MQConnectionFactory.setChannel(String)</i> would imply 'channel' property and
+ <i>com.ibm.mq.jms.MQConnectionFactory.setTransportType(int)</i> would imply 'transportType' property.
+ For the list of available properties please consult vendor provided documentation. Here is an example for
+ <a href="https://www-01.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm.mq.javadoc.doc/WMQJMSClasses/com/ibm/mq/jms/MQQueueConnectionFactory.html">IBM's com.ibm.mq.jms.MQConnectionFactory</a>

+<h2>Description:</h2>
+<p>
+ This ControllerService allows users to reference a JMS Connection Factory that has already been established and
+ made available via Java Naming and Directory Interface (JNDI) Server. Please see documentation from your JMS Vendor in order
+ to understand the appropriate values to configure for this service.
+</p>
+<p>
+ A Connection Factory in Java is typically obtained via JNDI in code like below. The comments have been added in to explain how
+ this maps to the Controller Service's configuration.
+</p>
+<pre>
+<code>
+Hashtable env = new Hashtable();
+env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_NAMING_FACTORY_CLASS); // Value for this comes from the "Initial Naming Factory Class" property.
+env.put(Context.PROVIDER_URL, NAMING_PROVIDER_URL); // Value for this comes from the "Naming Provider URL" property.
+env.put("My-Environment-Variable", "Environment-Variable-Value"); // This is accomplished by added a user-defined property with name "My-Environment-Variable" and value "Environment-Variable-Value"
+
+Context initialContext = new InitialContext(env);
+ConnectionFactory connectionFactory = initialContext.lookup(CONNECTION_FACTORY_NAME); // Value for Connection Factory name comes from "Connection Factory Name" property
+</code>
+</pre>
+
+<p>
+ It is also important to note that, in order for this to work, the class named by the Initial Naming Factory Class must be available on the classpath.
+ In NiFi, this is accomplished by setting the "Naming Factory Libraries" property to point to one or more .jar files or directories (comma-separated values).
+</p>
+
+<p>
+ When the Controller Service is disabled and then re-enabled, it will perform the JNDI lookup again. Once the Connection Factory has been obtained, though,
+ it will not perform another JNDI lookup until the service is disabled.
+</p>
+
+
+<h2>Example:</h2>
+
+<p>
+ As an example, the following configuration may be used to connect to Active MQ's JMS Broker, using the Connection Factory provided via their embedded JNDI server:
+</p>
+
+<table>
+ <thead>
+ <th>Property Name</th>
+ <th>Property Value</th>
+ </thead>
+ <tbody>
+ <tr>
+ <td>Initial Naming Factory Class</td>
+ <td>org.apache.activemq.jndi.ActiveMQInitialContextFactory</td>
+ </tr>
+ <tr>
+ <td>Naming Provider URL</td>
+ <td>tcp://jms-broker:61616</td>
+ </tr>
+ <tr>
+ <td>Connection Factory Name</td>
+ <td>ConnectionFactory</td>
+ </tr>
+ <tr>
+ <td>Naming Factory Libraries</td>
+ <td>/opt/apache-activemq-5.15.2/lib/</td>
+ </tr>
+ </tbody>
+</table>
+
+<p>
+ The above example assumes that there exists as host that is accessible with hostname "jms-broker" and that is running Apache ActiveMQ on port 61616 and also that
+ the jar containing the org.apache.activemq.jndi.ActiveMQInitialContextFactory class can be found within the /opt/apache-activemq-5.15.2/lib/ directory.

+ <!-- Processor Documentation ================================================== -->
+ <h2>Description:</h2>
+ <p>
+ This Processor polls <a href="http://kafka.apache.org/">Apache Kafka</a>
+ for data using KafkaConsumer API available with Kafka 0.10.x. When a message is received
+ from Kafka, the message will be deserialized using the configured Record Reader, and then
+ written to a FlowFile by serializing the message with the configured Record Writer.
+ </p>
+ <h2>Security Configuration:</h2>
+ <p>
+ The Security Protocol property allows the user to specify the protocol for communicating
+ with the Kafka broker. The following sections describe each of the protocols in further detail.
+ </p>
+ <h3>PLAINTEXT</h3>
+ <p>
+ This option provides an unsecured connection to the broker, with no client authentication and no encryption.
+ In order to use this option the broker must be configured with a listener of the form:
+ <pre>
+ PLAINTEXT://host.name:port
+ </pre>
+ </p>
+ <h3>SSL</h3>
+ <p>
+ This option provides an encrypted connection to the broker, with optional client authentication. In order
+ to use this option the broker must be configured with a listener of the form:
+ <pre>
+ SSL://host.name:port
+ </pre>
+ In addition, the processor must have an SSL Context Service selected.
+ </p>
+ <p>
+ If the broker specifies ssl.client.auth=none, or does not specify ssl.client.auth, then the client will
+ not be required to present a certificate. In this case, the SSL Context Service selected may specify only
+ a truststore containing the public key of the certificate authority used to sign the broker's key.
+ </p>
+ <p>
+ If the broker specifies ssl.client.auth=required then the client will be required to present a certificate.
+ In this case, the SSL Context Service must also specify a keystore containing a client key, in addition to
+ a truststore as described above.
+ </p>
+ <h3>SASL_PLAINTEXT</h3>
+ <p>
+ This option uses SASL with a PLAINTEXT transport layer to authenticate to the broker. In order to use this
+ option the broker must be configured with a listener of the form:
+ <pre>
+ SASL_PLAINTEXT://host.name:port
+ </pre>
+ In addition, the Kerberos Service Name must be specified in the processor.
+ </p>
+ <h4>SASL_PLAINTEXT - GSSAPI</h4>
+ <p>
+ If the SASL mechanism is GSSAPI, then the client must provide a JAAS configuration to authenticate. The
+ JAAS configuration can be provided by specifying the java.security.auth.login.config system property in
+ NiFi's bootstrap.conf, such as:
+ <pre>
+ java.arg.16=-Djava.security.auth.login.config=/path/to/kafka_client_jaas.conf
+ </pre>
+ </p>
+ <p>
+ An example of the JAAS config file would be the following:
+ <pre>
+ KafkaClient {
+ com.sun.security.auth.module.Krb5LoginModule required
+ useKeyTab=true
+ storeKey=true
+ keyTab="/path/to/nifi.keytab"
+ serviceName="kafka"
+ principal="nifi@YOURREALM.COM";
+ };
+ </pre>
+ <b>NOTE:</b> The serviceName in the JAAS file must match the Kerberos Service Name in the processor.
+ </p>
+ <p>
+ Alternatively, starting with Apache NiFi 1.2.0 which uses the Kafka 0.10.2 client, the JAAS
+ configuration when using GSSAPI can be provided by specifying the Kerberos Principal and Kerberos Keytab
+ directly in the processor properties. This will dynamically create a JAAS configuration like above, and
+ will take precedence over the java.security.auth.login.config system property.
+ </p>
+ <h4>SASL_PLAINTEXT - PLAIN</h4>
+ <p>
+ If the SASL mechanism is PLAIN, then client must provide a JAAS configuration to authenticate, but
+ the JAAS configuration must use Kafka's PlainLoginModule. An example of the JAAS config file would
+ be the following:
+ <pre>
+ KafkaClient {
+ org.apache.kafka.common.security.plain.PlainLoginModule required
+ username="nifi"
+ password="nifi-password";
+ };
+ </pre>
+ </p>
+ <p>
+ <b>NOTE:</b> It is not recommended to use a SASL mechanism of PLAIN with SASL_PLAINTEXT, as it would transmit
+ the username and password unencrypted.
+ </p>
+ <p>
+ <b>NOTE:</b> Using the PlainLoginModule will cause it be registered in the JVM's static list of Providers, making
+ it visible to components in other NARs that may access the providers. There is currently a known issue
+ where Kafka processors using the PlainLoginModule will cause HDFS processors with Keberos to no longer work.
+ </p>
+ <h3>SASL_SSL</h3>
+ <p>
+ This option uses SASL with an SSL/TLS transport layer to authenticate to the broker. In order to use this
+ option the broker must be configured with a listener of the form:
+ <pre>
+ SASL_SSL://host.name:port
+ </pre>
+ </p>
+ <p>
+ See the SASL_PLAINTEXT section for a description of how to provide the proper JAAS configuration
+ depending on the SASL mechanism (GSSAPI or PLAIN).
+ </p>
+ <p>
+ See the SSL section for a description of how to configure the SSL Context Service based on the
+ ssl.client.auth property.
+ </p>
+

to the 'parse.failure' relationship. Otherwise, each FlowFile is sent to the 'success' relationship and may contain many individual messages within the single FlowFile.
