[jira] [Commented] (HBASE-5373) Table level lock to prevent the race of multiple table level operation

I am glad that Alex is working this jira right now and I will help on the code-review. 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. -- This message is automatically generated by JIRA.

Basically, they put up a znode in ZK for any master-coordinated action, and it acts as an intent log of the idempotent steps. If there's a failover, the new master will finish off any already-running FATE transaction.

Sounds like what I try to do here. I will take a look over Accumulo.
