  • Apache Kafka Plugin

The plugin enables us to reliably and efficiently
stream large amounts of data/logs onto HBase
using the Phoenix API. Apache Kafka is a
distributed, partitioned, replicated commit log
service. It provides the functionality of a
messaging system, but with a unique design. So,
at a high level, producers send messages over the
network to the Kafka cluster which in turn serves
them up to consumers like this
We are providing PhoenixConsumer to recieves the
messages from Kafka Producer.

Create a kafka-consumer-regex.properties file
with below properties serializerregex serializer
.rowkeyTypeuuid serializer.regex(\,),(\,

  • Phoenix Consumer Execution Procedure
  • Start the Kakfa Producer then send some messages
  • bin/kafka-console-producer.sh --broker-list
    localhost9092 --topic topic1
  • Start the PhoenixConsumer using below command
  • HADOOP_CLASSPATH(hbase classpath)/path/to/hbase
    /conf hadoop jar phoenix-kafka-ltversiongt-minimal.j
    ar org.apache.phoenix.kafka.consumer.PhoenixConsum
    erTool --file /data/kafka-consumer.properties
  • The input file must be present on HDFS (not the
    local filesystem where the command is being run).

Configuration
Property Name Default Description
bootstrap.servers List of Kafka servers used to bootstrap connections to Kafka. This list should be in the form host1port1,host2port2,
topics List of topics to use as input for this connector. This list should be in the form topic1,topic2,
poll.timeout.ms 100 Default poll timeout in millisec
batchSize 100 Default number of events per transaction
zookeeper Quorum Zookeeper quorum of the HBase cluster
table The name of the table in HBase to write to.
ddl The CREATE TABLE query for the HBase table where the events will be upserted to. If specified, the query will be executed. Recommended to include the IF NOT EXISTS clause in the ddl.

Configuration
Property Name Default Description
serializer Event serializers for processing the Kafka Message.This Plugin supports all Phoenix Flume Event Serializers. Like regex, json
serializer.regex (.) The regular expression for parsing the message.
serializer.columns The columns that will be extracted from the Flume event for inserting into HBase.
serializer.headers Headers of the Flume Events that go as part of the UPSERT query. The data type for these columns are VARCHAR by default.
serializer.rowkeyType A custom row key generator . Can be one of timestamp,date,uuid,random and nanotimestamp. This should be configured in cases where we need a custom row key value to be auto generated and set for the primary key column.
