Configure Goldengate to Replicate data to Kafka

In this article we would configure Oracle GoldenGate for Big Data Kafka Handler to replicate change capture data from a Oracle GoldenGate trail to a Kafka topic. We would use 2 different servers, hosing multiple applications. Please find below details:-

Host      : fangorn.oradba.com
Database  : Oracle 11gR2
GG        : Oracle GoldenGate (12.2.0.1.0) 

Host      : hyd01db001.oradba.com
Zookeeper : zookeeper-3.4.10
Kafka     : Kafka 2.11-0.11
GG        : Oracle GoldenGate for Big Data (12.2.0.1.0)

Note: Throughout the entire installation and configuration, my OS user is "oracle" on both servers, unless mentioned.

Update host entries on both server:-

[oracle@fangorn ~]$ sudo su - 
[root@fangorn ~]# vi /etc/hosts
172.3.21.102   hyd01db001.oradba.com    hyd01db001
172.3.21.32    fangorn.oradba.com       fangorn

Then copy the same /etc/hosts file on hyd01db001 server as well

[root@fangorn ~]# scp /etc/hosts root@172.3.21.102:/etc/
