[jira] [Created] (HBASE-16144) Replication queue's lock will live forever if RS acquiring the lock has dead

Phil Yang created HBASE-16144:
---------------------------------

             Summary: Replication queue's lock will live forever if RS acquiring the lock has dead
                 Key: HBASE-16144
                 URL: https://issues.apache.org/jira/browse/HBASE-16144
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.20, 1.1.5, 1.2.1
            Reporter: Phil Yang
            Assignee: Phil Yang


In default, we will use multi operation when we claimQueues from ZK. But if we set hbase.zookeeper.useMulti=false, we will add a lock first, then copy nodes, finally clean old queue and the lock. 

However, if the RS acquiring the lock crash before claimQueues done, the lock will always be there and other RS can never claim the queue.
