Duo Zhang commented on HBASE-21237: ----------------------------------- Any updates here [~allan163]? > 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: 2.1.0, 2.0.2 > Reporter: Allan Yang > Assignee: Allan Yang > Priority: Major > Fix For: 2.0.3 > > Attachments: HBASE-21237.branch-2.0.001.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
