StateTransferOverwriteTest random failures ------------------------------------------ Key: ISPN-4368 URL: https://issues.jboss.org/browse/ISPN-4368 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 7.0.0.Alpha4 Reporter: Dan Berindei Assignee: William Burns Labels: testsuite_stability Fix For: 7.0.0.Beta1 {{testStateTransferInBetweenPrepareCommitWithPutCreate}} sometimes fails because the state transfer doesn't finish in time: {noformat} java.lang.RuntimeException: Timed out waiting for rebalancing to complete on node NodeBN-23267, current topology is CacheTopology{id=6, currentCH=DefaultConsistentHash{numSegments=60, numOwners=2, members=[NodeBM-52725, NodeBN-23267]}, pendingCH=DefaultConsistentHash{numSegments=60, numOwners=2, members=[NodeBM-52725, NodeBN-23267]}, unionCH=DefaultConsistentHash{numSegments=60, numOwners=2, members=[NodeBM-52725, NodeBN-23267]}} at org.infinispan.test.TestingUtil.waitForRehashToComplete(TestingUtil.java:214) at org.infinispan.distribution.rehash.BaseTxStateTransferOverwriteTest.doStateTransferInBetweenPrepareCommit(BaseTxStateTransferOverwriteTest.java:265) at org.infinispan.distribution.rehash.BaseTxStateTransferOverwriteTest.testStateTransferInBetweenPrepareCommitWithPutCreate(BaseTxStateTransferOverwriteTest.java:94) {noformat} The problem seems to be that the test intends to block the {{PUT_CREATE}} command on the primary owner of the test key, but it sometimes also blocks the state transfer put for the {{placeholder}} key - depending on which node was the backup owner of the {{placeholder}} key. The purpose of the {{placeholder}} key is also not very clear, we should add a comment how we expect the presence of another entry to interact with the tx / operation in progress.
