             Summary: 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
             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.
