Hi @Achu Thambi,

Can you verify that Zookeeper is installed and running correctly on the cluster?

From this answer: Ambari and ps command can show you that ZK service and ZK process is running on respective nodes, but only after "zkService.sh status" shows you that one node is the leader and the others are followers you can be absolutely certain that ZK is running and fully functional. You can run it using pdsh and targeting only ZK nodes.

Hi @Ward Bekker

Thanks for the reply..My zookeper is installed and running perfectly on my cluster..Not only zookeeper rest all services are working correctly except Hbase.

Also region servers are Live in Hbase..Hbase master will get stopped quickly whenever we restart the service.
