Phabricator updated HBASE-5542:
-------------------------------
Attachment: HBASE-5542.D2217.4.patch
sc updated the revision "HBASE-5542 [jira] Unify HRegion.mutateRowsWithLocks()
and HRegion.processRow()".
Reviewers: tedyu, lhofhansl, JIRA
I made several changes in this update.
1. Add the post and pre process hook as suggested by Lars
2. RowProcessorProtocol and BaseRowProcessorEndpoint
3. Some refactor and renaming
I add back the method RowProcessorProtocol.process(RowProcessor).
I did this because I figured out the user can make their RowProcessor
implementations as the inner classes of the endpoint.
This way RowProcessor can be class-loaded with the endpoint.
I have documented in the javadoc.
The example can be found in the unit test.

> mutateRowsWithLocks() does atomic mutations on multiple rows.
> processRow() does atomic read-modify-writes on a single row.
> It will be useful to generalize both and have a
> processRowsWithLocks() that does atomic read-modify-writes on multiple rows.
> This also helps reduce some redundancy in the codes.
