Cloudera Kafka Integration

• Install CSD
  Installation of the CSD will add a new parcel repository to your Cloudera Manager configuration.

sudo mkdir -p /opt/cloudera/csdsudo cp KAFKA-1.2.0.jar /opt/cloudera/csd/sudo /opt/cloudera-manager/cm-5.3.0/etc/init.d/cloudera-scm-server restart

• Log into the Cloudera Manager Admin Console and restart the Cloudera Management Service
• Download, distribute, and activate the parcel (You do not need to restart the cluster after installing Kafka.)
• add a service

kafka settings:

log.dirs = /var/local/kafka/data

Operations:

sudo kafka-topics --create --zookeeper zookeeper-server:2181 --topic activity --partitions 1 --replication-factor 1
