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

             Summary: Add coprocessor hooks for preWALAppend and postWALAppend
                 Key: HBASE-22623
                 URL: https://issues.apache.org/jira/browse/HBASE-22623
             Project: HBase
          Issue Type: New Feature
            Reporter: Geoffrey Jacoby
            Assignee: Geoffrey Jacoby


While many coprocessor hooks expose the WALEdit to implementing coprocs, there aren't any that expose the WALKey before it's created and added to the WALEntry. 

It's sometimes useful for coprocessors to be able to edit the WALKey, for example to add extended attributes using the fields to be added in HBASE-22622.
