----------------------------------
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.
