             Summary: Use CompatRemoteProcedureResolver to dispatch open/close region requests to RS
                 Key: HBASE-21237
                 URL: https://issues.apache.org/jira/browse/HBASE-21237
             Project: HBase
          Issue Type: Sub-task
    Affects Versions: 2.0.2, 2.1.0
            Reporter: Allan Yang
            Assignee: Allan Yang


As discussed in HBASE-21217, in branch-2.0 and branch-2.1, we should use  CompatRemoteProcedureResolver  instead of ExecuteProceduresRemoteCall to dispatch region open/close requests to RS. Since ExecuteProceduresRemoteCall  will group all the open/close operations in one call and execute them sequentially on the target RS. If one operation fails, all the operation will be marked as failure. Actually, some of the operations(like open region) is already executing in the open region handler thread. But master thinks these operations fails and reassign the regions to another RS. So when the previous RS report to the master that the region is online, master will kill the RS since it already assign the region to another RS.
For branch-2.2+, HBASE-21217 will fix this issue.
