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.
below string incorrectly defines zookeeper znode as "hbase" instead of "/hbase"...
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.
