+ <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>Summary</h2>
+<p>
+ This processor consumes messages from JMS compliant messaging system and converts them to a FlowFile to be routed to the next component in the flow.
+</p>
+<p>
+ This processor does two things. It constructs FlowFile by extracting information from the consumed JMS message including body, standard
+ <a href="http://docs.spring.io/spring-integration/docs/4.2.0.RELEASE/api/org/springframework/integration/jms/JmsHeaders.html">JMS Headers</a> and Properties.
+ The message body is written to a FlowFile while standard JMS Headers and Properties are set as FlowFile attributes.
+</p>
+
+<h2>Configuration Details</h2>
+<p>
+ At the time of writing this document it only defines the essential configuration properties which are suitable for most cases.
+ Other properties will be defined later as this component progresses.
+ Configuring ConsumeJMS:
+</p>
+<ol>
+ <li><b>User Name</b> - [OPTIONAL] User Name used for authentication and authorization when this processor obtains <i>javax.jms.Connection</i>
+ from the pre-configured <i>javax.jms.ConnectionFactory</i> (see below).
+ </li>
+ <li><b>Password</b> - [OPTIONAL] Password used in conjunction with <b>User Name</b>.
+ </li>
+ <li><b>Destination Name</b> - [REQUIRED] the name of the <i>javax.jms.Destination</i>.
+ Usually provided by administrator (e.g., 'topic://myTopic').
+ </li>
+ <li><b>Destination Type</b> - [REQUIRED] the type of the <i>javax.jms.Destination</i>. Could be one of 'QUEUE' or 'TOPIC'
+ Usually provided by the administrator. Defaults to 'QUEUE'.
+ </li>
+ <li><b>Connection Factory Service</b> - [REQUIRED] link to a pre-configured instance of org.apache.nifi.jms.cf.JMSConnectionFactoryProvider.

+<h2>Summary</h2>
+<p>
+ This processor publishes the contents of the incoming FlowFile to a JMS compliant messaging system.
+</p>
+<p>
+ This processor does two things. It constructs JMS Message by extracting FlowFile contents (both body and attributes).
+ Once message is constructed it is sent to a pre-configured JMS Destination.
+ Standard <a href="http://docs.spring.io/spring-integration/docs/4.2.0.RELEASE/api/org/springframework/integration/jms/JmsHeaders.html">JMS Headers</a>
+ will be extracted from the FlowFile and set on <i>javax.jms.Message</i> as JMS headers while other
+ FlowFile attributes will be set as properties of <i>javax.jms.Message</i>. Upon success the incoming FlowFile is transferred
+ to the <i>success</i> Relationship and upon failure FlowFile is
+ penalized and transferred to the <i>failure</i> Relationship.
+</p>
+<h2>Configuration Details</h2>
+<p>
+ At the time of writing this document it only defines the essential configuration properties which are suitable for most cases.
+ Other properties will be defined later as this component progresses.
+ Configuring PublishJMS:
+</p>
+<ol>
+ <li><b>User Name</b> - [OPTIONAL] User Name used for authentication and authorization when this processor obtains <i>javax.jms.Connection</i>
+ from the pre-configured <i>javax.jms.ConnectionFactory</i> (see below).
+ </li>
+ <li><b>Password</b> - [OPTIONAL] Password used in conjunction with <b>User Name</b>.
+ </li>
+ <li><b>Destination Name</b> - [REQUIRED] the name of the <i>javax.jms.Destination</i>.
+ Usually provided by administrator (e.g., 'topic://myTopic').
+ </li>
+ <li><b>Destination Type</b> - [REQUIRED] the type of the <i>javax.jms.Destination</i>. Could be one of 'QUEUE' or 'TOPIC'
+ Usually provided by the administrator. Defaults to 'QUEUE'.
+ </li>
+ <li><b>Connection Factory Service</b> - [REQUIRED] link to a pre-configured instance of org.apache.nifi.jms.cf.JMSConnectionFactoryProvider.

+ <!-- 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>

+ <body>
+ <!-- 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, this Processor emits a FlowFile where the content of the FlowFile is the value
+ of the Kafka message.
+ </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>
