Hudson commented on HBASE-20137: -------------------------------- FAILURE: Integrated in Jenkins build HBase-Trunk_matrix #4708 (See [https://builds.apache.org/job/HBase-Trunk_matrix/4708/]) Revert "HBASE-20137 TestRSGroups is flakey" (stack: rev 37d91cdfbb7dcfd46a72d328706cca5a39871381) * (edit) hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestAssignmentManager.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/FailedRemoteDispatchException.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java > TestRSGroups is flakey > ---------------------- > > Key: HBASE-20137 > URL: https://issues.apache.org/jira/browse/HBASE-20137 > Project: HBase > Issue Type: Bug > Components: flakey > Affects Versions: 2.0.0-beta-2 > Reporter: stack > Assignee: stack > Priority: Major > Fix For: 2.0.0 > > Attachments: HBASE-20137.branch-2.001.patch, > HBASE-20137.branch-2.002.patch, HBASE-20137.branch-2.003.patch, > HBASE-20137.branch-2.003.patch > > > It was the single test that failed the hbase-2 nightlies in #440 at the > hadoop2 stage. > The failure manifests as a timeout. It actually has an interesting cause > calling into question some of the clauses in > UnassignProcedure#remoteCallFailed. > We are running a disabletable concurrent with a shutdown. pid=309 is the > disable. pid=311 is the interesting one. The below is a little hard to read > -- the exception 'message' is the the current procedure as a String... hard > to parse, fixing -- but we are trying to unassign as part of a the > disabletable. Our RPC fails because the server we are trying to rpc too is > currently being processed as crashed (pid=308 is a servercrashprocedure for > this server). As part of the processing of the failed RPC we will expire the > server -- if we can't RPC to it, it must be gone. The current procedure is > then suspended until it gets woken up by the servercrashprocedure triggered > by the expire.... only in this case we are shutting down so the expire is > ignored... The current procedure is left in its suspend state. This prevents > the Master going down. So we time out. > 2018-03-05 11:29:22,507 INFO [PEWorker-13] > assignment.RegionTransitionProcedure(213): Dispatch pid=311, ppid=309, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=Group_ns:testKillRS, region=de7534c208a06502537cd95c248b3043, > server=1cfd208ff882,40584,1520249102524; rit=CLOSING, > location=1cfd208ff882,40584,1520249102524 > 2018-03-05 11:29:22,508 WARN [PEWorker-13] > assignment.RegionTransitionProcedure(187): Remote call failed pid=311, > ppid=309, state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=Group_ns:testKillRS, region=de7534c208a06502537cd95c248b3043, > server=1cfd208ff882,40584,1520249102524; rit=CLOSING, > location=1cfd208ff882,40584,1520249102524; exception=pid=311, ppid=309, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=Group_ns:testKillRS, region=de7534c208a06502537cd95c248b3043, > server=1cfd208ff882,40584,1520249102524 to 1cfd208ff882,40584,1520249102524 > 2018-03-05 11:29:22,508 WARN [PEWorker-13] > assignment.UnassignProcedure(276): Expiring server pid=311, ppid=309, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=Group_ns:testKillRS, region=de7534c208a06502537cd95c248b3043, > server=1cfd208ff882,40584,1520249102524; rit=CLOSING, > location=1cfd208ff882,40584,1520249102524, > exception=org.apache.hadoop.hbase.master.assignment.FailedRemoteDispatchException: > pid=311, ppid=309, state=RUNNABLE:REGION_TRANSITION_DISPATCH; > UnassignProcedure table=Group_ns:testKillRS, > region=de7534c208a06502537cd95c248b3043, > server=1cfd208ff882,40584,1520249102524 to 1cfd208ff882,40584,1520249102524 > 2018-03-05 11:29:22,508 WARN [PEWorker-13] master.ServerManager(580): > Expiration of 1cfd208ff882,40584,1520249102524 but server shutdown already in > progress > I need to cater for case where the expire server is rejected. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
