JGroups fails to install new cluster view after coordinator leave ----------------------------------------------------------------- Key: ISPN-9588 URL: https://issues.redhat.com/browse/ISPN-9588 Project: Infinispan Issue Type: Bug Components: Core, Test Suite Affects Versions: 9.4.0.CR3 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 9.4.7.Final, 10.0.0.Beta1 Attachments: ISPN-9127_ScatteredCrashInSequenceTest-infinispan-core.log.gz, ISPN-9127_ThreeWaySplitAndMergeTest-infinispan-core.log.gz, ThreeWaySplitAndMergeTest.clearContent.log.gz The core test suite normally shuts down cache managers in the reverse order of their start, so that the coordinator stops last. This should be just an optimization, to reduce the number of coordinator changes, and with it the test suite duration and log size. Unfortunately, the few tests that stop the coordinator first are routinely failing to stop the cluster properly, usually when there are 2 nodes left in the cluster the 2nd node doesn't receive the view: {noformat} 10:08:01,656 DEBUG (jgroups-26,Test-NodeB-20661:[]) [GMS] Test-NodeB-20661: installing view [Test-NodeC-25266|33] (3) [Test-NodeC-25266, Test-NodeA-8936, Test-NodeB-20661] 10:08:01,862 TRACE (testng-Test:[]) [GMS] Test-NodeC-25266: sending LEAVE request to Test-NodeA-8936 10:08:01,863 DEBUG (jgroups-6,Test-NodeA-8936:[]) [GMS] Test-NodeA-8936: members are (3) Test-NodeC-25266,Test-NodeA-8936,Test-NodeB-20661, coord=Test-NodeA-8936: I'm the new coordinator 10:08:01,896 TRACE (jgroups-6,Test-NodeA-8936:[]) [GMS] Test-NodeA-8936: joiners=[], suspected=[], leaving=[Test-NodeC-25266], new view: [Test-NodeA-8936|34] (2) [Test-NodeA-8936, Test-NodeB-20661] 10:08:01,896 TRACE (jgroups-6,Test-NodeA-8936:[]) [GMS] Test-NodeA-8936: mcasting view [Test-NodeA-8936|34] (2) [Test-NodeA-8936, Test-NodeB-20661] 10:08:01,900 DEBUG (jgroups-6,Test-NodeA-8936:[]) [GMS] Test-NodeA-8936: installing view [Test-NodeA-8936|34] (2) [Test-NodeA-8936, Test-NodeB-20661] 10:08:02,245 TRACE (testng-Test:[]) [JGroupsTransport] Test-NodeB-20661 sending request 140 to Test-NodeC-25266: CacheTopologyControlCommand{cache=org.infinispan.CONFIG, type=LEAVE, sender=Test-NodeB-20661, joinInfo=null, topologyId=0, rebalanceId=0, currentCH=null, pendingCH=null, availabilityMode=null, phase=null, actualMembers=null, throwable=null, viewId=33} 10:12:02,247 DEBUG (testng-Test:[]) [LocalTopologyManagerImpl] Error sending the leave request for cache org.infinispan.CONFIG to coordinator org.infinispan.util.concurrent.TimeoutException: ISPN000476: Timed out waiting for responses for request 140 from 7d5d965d-eacc-fd47-2ab8-5cec95f4c10b {noformat} Sometimes the new coordinator gets stuck in a merge loop, keeps trying to re-include the stopped node and fails: {noformat} 10:06:21,484 DEBUG (jgroups-24,Test-NodeC-57941:[]) [GMS] Test-NodeC-57941: installing view [Test-NodeD-37696|8] (3) [Test-NodeD-37696, Test-NodeB-39137, Test-NodeC-57941] 10:06:21,486 DEBUG (jgroups-25,Test-NodeB-39137:[]) [GMS] Test-NodeB-39137: installing view [Test-NodeD-37696|8] (3) [Test-NodeD-37696, Test-NodeB-39137, Test-NodeC-57941] 10:06:22,070 TRACE (testng-Test:[]) [GMS] Test-NodeD-37696: sending LEAVE request to Test-NodeB-39137 10:06:22,078 TRACE (jgroups-10,Test-NodeB-39137:[]) [GMS] Test-NodeB-39137: mcasting view [Test-NodeB-39137|9] (2) [Test-NodeB-39137, Test-NodeC-57941] 10:06:22,080 DEBUG (jgroups-10,Test-NodeB-39137:[]) [GMS] Test-NodeB-39137: installing view [Test-NodeB-39137|9] (2) [Test-NodeB-39137, Test-NodeC-57941] 10:06:30,887 DEBUG (jgroups-24,Test-NodeB-39137:[]) [GMS] Test-NodeB-39137: I will be the merge leader.
