The content of a FlowFile becomes the contents of a Kafka message. + This message is optionally assigned a key by using the <Kafka Key> Property. + </p> + + <p> + The Processor allows the user to configure an optional Message Demarcator that + can be used to send many messages per FlowFile. For example, a <i>\n</i> could be used + to indicate that the contents of the FlowFile should be used to send one message + per line of text. It also supports multi-char demarcators (e.g., 'my custom demarcator'). + If the property is not set, the entire contents of the FlowFile + will be sent as a single message. When using the demarcator, if some messages are + successfully sent but other messages fail to send, the resulting FlowFile will be + considered a failed FlowFile and will have additional attributes to that effect. + One of such attributes is 'failed.last.idx' which indicates the index of the last message + that was successfully ACKed by Kafka. (if no demarcator is used the value of this index will be -1). + This will allow PublishKafka to only re-send un-ACKed messages on the next re-try. + </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, 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> Added: nifi/site/trunk/docs/nifi-docs/components/org.apache.nifi/nifi-kafka-1-0-nar/1.7.0/org.apache.nifi.processors.kafka.pubsub.PublishKafka_1_0/index.html URL: http://svn.apache.org/viewvc/nifi/site/trunk/docs/nifi-docs/components/org.apache.nifi/nifi-kafka-1-0-nar/1.7.0/org.apache.nifi.processors.kafka.pubsub.PublishKafka_1_0/index.html?rev=1834461&view=auto ============================================================================== --- nifi/site/trunk/docs/nifi-docs/components/org.apache.nifi/nifi-kafka-1-0-nar/1.7.0/org.apache.nifi.processors.kafka.pubsub.PublishKafka_1_0/index.html (added) +++ nifi/site/trunk/docs/nifi-docs/components/org.apache.nifi/nifi-kafka-1-0-nar/1.7.0/org.apache.nifi.processors.kafka.pubsub.PublishKafka_1_0/index.html Wed Jun 27 00:37:46 2018 @@ -0,0 +1 @@ +<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"></meta><title>PublishKafka_1_0</title><link rel="stylesheet" href="../../../../../css/component-usage.css" type="text/css"></link></head><script type="text/javascript">window.onload = function(){if(self==top) { document.getElementById('nameHeader').style.display = "inherit"; } }</script><body><h1 id="nameHeader" style="display: none;">PublishKafka_1_0</h1><h2>Description: </h2><p>Sends the contents of a FlowFile as a message to Apache Kafka using the Kafka 1.0 Producer API.The messages to send may be individual FlowFiles or may be delimited, using a user-specified delimiter, such as a new-line.

The processor will use the Kite SDK to make an attempt to automatically generate an Avro schema from the incoming content. When inferring the schema from JSON data the key names will be used in the resulting Avro schema definition. When inferring from CSV data a "header definition" must be present either as the first line of the incoming data or the "header definition" must be explicitly set in the property "CSV Header Definition". A "header definition" is simply a single comma se parated line defining the names of each column. The "header definition" is required in order to determine the names that should be given to each field in the resulting Avro definition. When inferring data types the higher order data type is always used if there is ambiguity. For example when examining numerical values the type may be set to "long" instead of "integer" since a long can safely hold the value of any "integer". Only CSV and JSON content is currently supported for automatically inferring an Avro schema. The type of content present in the incoming FlowFile is set by using the property "Input Content Type". The property can either be explicitly set to CSV, JSON, or "use mime.type value" which will examine the value of the mime.type attribute on the incoming FlowFile to determine the type of content present.</p><h3>Tags: </h3><p>kite, avro, infer, schema, csv, json</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong> .
