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

             Summary: Introducing "recovering" region state to mark a region in recovering
status used in distributedLogReplay
                 Key: HBASE-8234
                 URL: https://issues.apache.org/jira/browse/HBASE-8234
             Project: HBase
          Issue Type: Sub-task
            Reporter: Jeffrey Zhong


There are two advantages to have this new "recovering" state for a region:

1) Instead of mark a region "recovering" in ZK, we can consolidate all region states in one
place and be aware by assignment manager
2) When handing disabling table, we have to have this new state so that regions of a disabling
table can be transitioned into this state for recovering.

Notes:
In the initial release of distributed log replay, we may not do this subtask for simplifications.
Without the new state, we still need to create recovered edits files for regions of a disabling
table. With the new state, we can retire recover edits files creation business totally.
