> Project: HBase
> Issue Type: Sub-task
> Affects Versions: 2.1.0, 2.0.2

> 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.
