stack updated HBASE-20202: -------------------------- Attachment: HBASE-20202.branch-2.003.patch > [AMv2] Don't move region if its a split parent or offlined > ---------------------------------------------------------- > > Key: HBASE-20202 > URL: https://issues.apache.org/jira/browse/HBASE-20202 > Project: HBase > Issue Type: Sub-task > Components: amv2 > Affects Versions: 2.0.0-beta-2 > Reporter: stack > Assignee: stack > Priority: Critical > Fix For: 2.0.0 > > Attachments: HBASE-20202.branch-2.001.patch, > HBASE-20202.branch-2.002.patch, HBASE-20202.branch-2.003.patch, > HBASE-20202.branch-2.003.patch > > > Found this one running ITBLLs. We'd just finished splitting a region > 91655de06786f786b0ee9c51280e1ee6 and then a move for it comes in. The move > fails in an interesting way. The location has been removed from the > regionnode kept by the Master. HBASE-20178 adds macro checks on context. Need > to add a few checks to the likes of MoveRegionProcedure so we don't try to > move an offlined/split parent. > {code} > 2018-03-14 10:21:45,678 INFO [PEWorker-2] procedure2.ProcedureExecutor: > Finished pid=3177, state=SUCCESS; SplitTableRegionProcedure > table=IntegrationTestBigLinkedList, parent=91655de06786f786b0ee9c51280e1ee6, > daughterA=b67bf6b79eaa83de788b0519f782ce8e, > daughterB=99cf6ddb38cad08e3aa7635b6cac2e7b in 10.0210sec > 2018-03-14 10:21:45,679 INFO [PEWorker-15] > procedure.MasterProcedureScheduler: pid=3194, ppid=3193, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=IntegrationTestBigLinkedList, region=af198ca64b196fb3d2f5b3e815b2dad0, > server=ve0530.halxg.cloudera.com,16020,1521007509855, > IntegrationTestBigLinkedList,\xAA\xAA\xAA\xAA\xAA\xAA\xAA\xA0,1521047891276.af198ca64b196fb3d2f5b3e815b2dad0. > 2018-03-14 10:21:45,680 INFO [PEWorker-5] > procedure.MasterProcedureScheduler: pid=3187, > state=RUNNABLE:MOVE_REGION_UNASSIGN; MoveRegionProcedure > hri=IntegrationTestBigLinkedList,\x0C0\xC3\x0C0\xC3\x0C0,1521045713137.91655de06786f786b0ee9c51280e1ee6., > source=ve0530.halxg.cloudera.com,16020,1521007509855, > destination=ve0528.halxg.cloudera.com,16020,1521047890874, > IntegrationTestBigLinkedList,\x0C0\xC3\x0C0\xC3\x0C0,1521045713137.91655de06786f786b0ee9c51280e1ee6. > 2018-03-14 10:21:45,680 INFO [PEWorker-15] assignment.RegionStateStore: > pid=3194 updating hbase:meta > row=IntegrationTestBigLinkedList,\xAA\xAA\xAA\xAA\xAA\xAA\xAA\xA0,1521047891276.af198ca64b196fb3d2f5b3e815b2dad0., > regionState=CLOSING > 2018-03-14 10:21:45,680 INFO [PEWorker-5] procedure2.ProcedureExecutor: > Initialized subprocedures=[{pid=3195, ppid=3187, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=IntegrationTestBigLinkedList, region=91655de06786f786b0ee9c51280e1ee6, > server=ve0530.halxg.cloudera.com,16020,1521007509855}] > 2018-03-14 10:21:45,683 INFO [PEWorker-15] > assignment.RegionTransitionProcedure: Dispatch pid=3194, ppid=3193, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=IntegrationTestBigLinkedList, region=af198ca64b196fb3d2f5b3e815b2dad0, > server=ve0530.halxg.cloudera.com,16020,1521007509855; rit=CLOSING, > location=ve0530.halxg.cloudera.com,16020,1521007509855 > 2018-03-14 10:21:45,752 INFO [PEWorker-15] > procedure.MasterProcedureScheduler: pid=3195, ppid=3187, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=IntegrationTestBigLinkedList, region=91655de06786f786b0ee9c51280e1ee6, > server=ve0530.halxg.cloudera.com,16020,1521007509855, > IntegrationTestBigLinkedList,\x0C0\xC3\x0C0\xC3\x0C0,1521045713137.91655de06786f786b0ee9c51280e1ee6. > 2018-03-14 10:21:45,753 ERROR [PEWorker-15] procedure2.ProcedureExecutor: > CODE-BUG: Uncaught runtime exception: pid=3195, ppid=3187, > state=RUNNABLE:REGION_TRANSITION_DISPATCH; UnassignProcedure > table=IntegrationTestBigLinkedList, region=91655de06786f786b0ee9c51280e1ee6, > server=ve0530.halxg.cloudera.com,16020,1521007509855 > java.lang.NullPointerException > > > > at > java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) > at > org.apache.hadoop.hbase.master.assignment.RegionStates.getOrCreateServer(RegionStates.java:934) > at > org.apache.hadoop.hbase.master.assignment.RegionStates.addRegionToServer(RegionStates.java:962) > at > org.apache.hadoop.hbase.master.assignment.AssignmentManager.markRegionAsClosing(AssignmentManager.java:1548) > > > at > org.apache.hadoop.hbase.master.assignment.UnassignProcedure.updateTransition(UnassignProcedure.java:197) > at > org.apache.hadoop.hbase.master.assignment.RegionTransitionProcedure.execute(RegionTransitionProcedure.java:304) > > > at > org.apache.hadoop.hbase.master.assignment.RegionTransitionProcedure.execute(RegionTransitionProcedure.java:86) > at > org.apache.hadoop.hbase.procedure2.Procedure.doExecute(Procedure.java:845) > at > org.apache.hadoop.hbase.procedure2.ProcedureExecutor.execProcedure(ProcedureExecutor.java:1452) > at > org.apache.hadoop.hbase.procedure2.ProcedureExecutor.executeProcedure(ProcedureExecutor.java:1221) > at > org.apache.hadoop.hbase.procedure2.ProcedureExecutor.access$800(ProcedureExecutor.java:75) > at > org.apache.hadoop.hbase.procedure2.ProcedureExecutor$WorkerThread.run(ProcedureExecutor.java:1740) > > > > 2018-03-14 10:21:45,835 DEBUG [RSProcedureDispatcher-pool3-t22] > ipc.NettyRpcConnection: Connecting to > ve0530.halxg.cloudera.com/10.17.240.23:16020 > {code} > Will work on this after HBASE-20178 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
