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

TableLock is a broader one and we might delay other lock needed ops unwanted. This is my major concern.

Had some discussion with Jingcheng and some ways have come out.. He would add details.

Pls don't commit.

> We had a lock to synchronize the major compaction, and sweep tool. Now we will have MR-less mob compaction in the HBase, and need the lock as well. And the table lock is a better choice. In this JIRA, clean the MobZookeeper code and use TableLockManager instead.
