Nick Dimiduk created HBASE-25059:
------------------------------------

             Summary: TransitionRegionStateProcedure should timeout, rollback, 
retry instead of waiting infinitely on CONFIRMED_OPEN
                 Key: HBASE-25059
                 URL: https://issues.apache.org/jira/browse/HBASE-25059
             Project: HBase
          Issue Type: Bug
          Components: Region Assignment
    Affects Versions: 2.3.2
            Reporter: Nick Dimiduk


Testing 2.3.2RC1 with ITBLL. The region server assigned to open meta locked up 
due to HBASE-24896. Meanwhile, the master waits indefinitely on a procedure 
{{pid=176583, ppid=176532, 
state=WAITING:REGION_STATE_TRANSITION_CONFIRM_OPENED; 
TransitRegionStateProcedure table=hbase:meta, region=1588230740, ASSIGN}}.

AssignmentManager needs a way to rescind assignment when a RS fails to complete 
within a reasonable timeout window, roll back the procedure, and try again with 
a new target.
