----------------------------------------------
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.
