Table level lock to prevent the race of multiple table level operation
----------------------------------------------------------------------

                 Key: HBASE-5373
                 URL: https://issues.apache.org/jira/browse/HBASE-5373
             Project: HBase
          Issue Type: Improvement
            Reporter: Liyin Tang
            Assignee: Liyin Tang


A table level lock can guarantee that only one table operation would happen at one time for
each table. The master should require and release these table locks correctly during the failover
time. One proposal is to keep track of the lock and its corresponding operation in the zookeeper.
If there is a master failover, the secondary should have a way to check whether these operations
are succeeded nor not before releasing the lock.
