             Summary: Adding new hooks to the split flow - For roll backs and one final hook
after split is completed either successfully or failed
                 Key: HBASE-6633
                 URL: https://issues.apache.org/jira/browse/HBASE-6633
             Project: HBase
          Issue Type: Improvement
          Components: coprocessors
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan


Currently we have two hooks in the split flow of a region.  PreSplit() and postSplit().  But
not always these are helpful in case i have a problem in preSplit() or postSplit() i need
to do a rollback of the current region or the region that i am handling thro the hooks.

So its better if we have a hook in the rollback code and also one final hook say postCompleteSplit()
so that CP can take any corrective action.
Pls do suggest if i can provide a patch for this.
