      Description

      Here's the exception:

      ava.io.IOException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /hbase/master
             at org.apache.hadoop.hbase.zookeeper.ZooKeeperWrapper.readAddressOrThrow(ZooKeeperWrapper.java:332)

      If fixed in in trunk by removing it, but not in branch. Looking at it again, we could just log the message. Will change in branch and trunk.
