    Resolution: Duplicate

Resolving as duplicate.  Liyin, you did it first so I should be resolving 
HBASE-5494 as a duplicate of this but HBASE-5494 has a little bit more going 
on.  Hope you don't mind.   Are you working on this?

> 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.
