CDAP Replication Deployment

This document lists detailed steps required for setting up Replication for CDAP:

1. Setup hbase-site.xml on all nodes:

   1. These properties need to be added. Choose coprocessors based on the HBase version running on the cluster. In this example below its HBase 1.0. 
      
      

       <property>
       <name>hbase.replication</name>
       <value>true</value>
       </property>
       <property>
       <name>hbase.coprocessor.regionserver.classes</name>
       <value>co.cask.cdap.data2.replication.hbase10.LastReplicateTimeObserver</value>
       </property>
       <property>
       <name>hbase.coprocessor.wal.classes</name>
       <value>co.cask.cdap.data2.replication.hbase10.LastWriteTimeObserver</value>
       </property>

2. These steps are required for a secure cluster:
   1. Set up JAAS Configuration.
   2. Sync /etc/hosts on all the nodes
