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="[email protected]"; + }; + </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.

The contents of the incoming FlowFile will be read using the + configured Record Reader. Each record will then be serialized using the configured + Record Writer, and this serialized form will be the content of a Kafka message. + This message is optionally assigned a key by using the <Kafka Key> Property. + </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="[email protected]"; + }; + </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> +</html>
