Install the relevant cdap-hbase-compat package on all hbase nodes in your cluster . Compat packages are:
cdap-hbase-compat-0.96

cdap-hbase-compat-0.98

in order to use the replication status coprocessors. Note that due to HBase limitations, these coprocessors cannot be used on hbase 0.96 or 0.98. Compat packages are:

cdap-hbase-compat-1.0
cdap-hbase-compat-1.0-cdh
cdap-hbase-compat-1.0-cdh5.5.0
cdap-hbase-compat-1.1
cdap-hbase-compat-1.2-cdh5.7.0

Modify hbase-site.xml on all hbase nodes to enable hbase replication, and to use the CDAP replication status coprocessors

Code Block

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

Modify hbase-env.sh on all hbase nodes to include the hbase coprocessor in the classpath

Code Block

export HBASE_CLASSPATH="$HBASE_CLASSPATH:/opt/cdap/<hbase-compat-version>/coprocessor/*"
 
for example, if you're on cdh5.5.x and have installed the cdap-hbase-compat-1.0-cdh5.5.0 package:
export HBASE_CLASSPATH="$HBASE_CLASSPATH:/opt/cdap/hbase-compat-1.0-cdh5.5.0/coprocessor/*"

Restart hbase master and regionservers
