---------------------------------------------
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.
