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

             Summary: Should get the meta replica number from zk instead of 
config at client side
                 Key: HBASE-21658
                 URL: https://issues.apache.org/jira/browse/HBASE-21658
             Project: HBase
          Issue Type: Improvement
          Components: Client
            Reporter: Duo Zhang


For now, the ZKAsyncRegistry will use the znodePaths.metaReplicaZNodes for 
getting meta replicas. But actually, this config should only be used by 
HMaster. At client side, we should list the zk directory to get all the 
available meta replicas.
