stack updated HBASE-21075:
--------------------------
Release Note: hbase-2.2.x uses a new Procedure form
assiging/unassigning/moving Regions; it does not process hbase-2.1.x and
earlier Unassign/Assign Procedure types. Upgrade requires that we first drain
the Master Procedure Store of old style Procedures before starting the new
2.2.x Master. The patch here facilitates the draining process.
> Confirm that we can (rolling) upgrade from 2.0.x and 2.1.x to 2.2.x after
