    Hi Sushma,

    Do you have more than one zookeeper service configured and running?

    Thanks

    Can I stop the zookeeper service in Ambari UI and then delete the slave node which runs Zoo Keeper service ?. Will this effect the cluster ?

    Hi Sushma,

    If you really want to get rid of the zookeeper service, you can simply stop zookeeper service from Ambari UI and decommission the slave node. The impact will be:
    1. Any other service(s) running on that slave node.
    2. Any other service that depends on Zookeeper service, like hbase, namenode HA or Hive (If you use zk to lock the table).

    Thanks,
    Kenny
