ZKW.ensureExists should check for existence
-------------------------------------------
Key: HBASE-2262
URL: https://issues.apache.org/jira/browse/HBASE-2262
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Assignee: Jean-Daniel Cryans
Fix For: 0.20.4, 0.21.0
The fact that ZKW.ensureExists relies on KeeperException.NodeExistsException
creates a lot of chatter in HBase and Zookeeper logs and also confuses users.
We should use ZooKeeper.exists instead.
