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

                 Key: HBASE-3708
                 URL: https://issues.apache.org/jira/browse/HBASE-3708

    Affects Versions: 0.90.1
            Reporter: stack


Clients on startup create a ZKWatcher instance.  Part of construction is check that hbase
dirs are all up in zk.  Its done by making the following call: http://hbase.apache.org/xref/org/apache/hadoop/hbase/zookeeper/ZKUtil.html#898

A user complains that its making for lots of logging every second over on the zk ensemble:

14:59 ....seeing lots of these in the ZK log though, dozens per second of "Got user-level
KeeperException when processing sessionid:0x42daa1daab0ecbe type:create cxid:0x1 zxid:0xfffffffffffffffe
txntype:unknown reqpath:n/a Error Path:/hbase Error:KeeperErrorCode = NodeExists for /hbase"
