Date Fri, 11 Sep 2015 19:01:46 GMT

------------------------------
    Description: 
- Created replication peer POB3-HBASE-LL-A. By mistake used hyphens in the replication peer
name.
- Did {{remove_peer POB3-HBASE-LL-A}}
- Created a new peer POB3_HBASE_LL_A
- Verified zk for entries

Even though the peer got removed, there are still some ZK entries left which need to be cleaned.

  was:
- Created replication peer POB3-HBASE-LL-A. By mistake used hyphens in the replication peer
name.
- Did {{remove_peer POB3-HBASE-LL-A}}
- Created a new peer POB3_HBASE_LL_A
- Verified zk for entries
