Phabricator commented on HBASE-5515: ------------------------------------ lhofhansl has commented on the revision "HBASE-5515 [jira] Add a processRow API that supports atomic multiple reads and writes on a row". @sc: "It will be nice to have some API that can allows simple control on lock/mvcc. That will be very powerful." But you do not want to do it for this issue? ;-) My point is that a RowProcessor implementation class is what coprocessor endpoints were meant for (server side custom code) - with the caveat that coprocessors currently do not have enough access to regionserver details.
