             Summary: MoveProcedure can be subtask of ModifyTableProcedure/ReopenTableRegionsProcedure; ensure all kosher.
                 Key: HBASE-20682
                 URL: https://issues.apache.org/jira/browse/HBASE-20682
             Project: HBase
          Issue Type: Sub-task
          Components: amv2

            Assignee: stack


MoveProcedure is used in at least two places as a means of 'reopening' a region after a config has changed. This issue is about review of MP so this usage is first-class (and that MP is good procedure citizen running as a subprocedure. In question is what should happen if the source server or the target servers are offline when we go to run. As of the parent issue, we'll skip to the end. Should we instead go ahead with the move (internally, if we are asked to assign to an offline server, we'll pick another -- do same for unassign? Would help in this reopen use case).
