    Description

      When working on HBASE-20666, I found out HBASE-18350 did not get ported to branch-1, which causes procedure to hang when #moveTables called sometimes. 

      After looking into the 18350 patch, seems it's important since it fixes 4 issues. This Jira is an attempt to backport it to branch-1.

       

       

      Edited: Aug26.

      After reviewed the HBASE-18350 patch. I decided to only port part 2 of the patch.

      Because part1 and part3 is AMv2 related. I won't touch is since Amv2 is only for branch-2

       

       

      Subject: [PATCH] HBASE-18350 RSGroups are broken under AMv2

      • Table moving to RSG was buggy, because it left the table unassigned.
          Now it is fixed we immediately assign to an appropriate RS
          (MoveRegionProcedure).
        • Table was locked while moving, but unassign operation hung, because*
            locked table queues are not scheduled while locked. Fixed.   ---- port this one.
      • ProcedureSyncWait was buggy, because it searched the procId in
          executor, but executor does not store the return values of internal
          operations (they are stored, but immediately removed by the cleaner).
      • list_rsgroups in the shell show also the assigned tables and servers.
