------------------------------

             Summary: Perform validation on cluster key for add_peer
                 Key: HBASE-15769
                 URL: https://issues.apache.org/jira/browse/HBASE-15769
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


[~pateljaymin] reported the following.

In hbase cluster, adding a peer for replication, incorrectly defined zookeeper znode does not fail new peer creation. However, replication breaks down.

For example, 
below string incorrectly defines zookeeper znode as "hbase" instead of "/hbase"...
{code}
> add_peer '1', "host1.com,host2.com,host3.com:2181:hbase
{code}
This left replication broken, even after we dropped and added a new correct entry for the peer.

It wasn't until we bounced the cluster that the issue was fixed.
