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

             Summary: ZK watches leaks during snapshots
                 Key: HBASE-13885
                 URL: https://issues.apache.org/jira/browse/HBASE-13885
             Project: HBase
          Issue Type: Bug
          Components: snapshots
    Affects Versions: 0.98.12
            Reporter: Abhishek Singh Chouhan


When taking snapshot of a table a watcher over /hbase/online-snapshot/abort/snapshot-name
is created which is never cleared when the snapshot is successful. If we use snapshots to
take backups daily we accumulate a lot of watches.

Steps to reproduce -
1) Take snapshot of a table - snapshot 'table_1', 'abc'
2) Run the following on zk node or alternatively observe zk watches metric
 echo "wchc" | nc localhost 2181
/hbase/online-snapshot/abort/abc can be found.
