             Summary: Flaky failures in DynamicColumnsAbstractConcurrentSelfTest
                 Key: IGNITE-6440
                 URL: https://issues.apache.org/jira/browse/IGNITE-6440
             Project: Ignite
          Issue Type: Task
          Components: sql
    Affects Versions: 2.3
            Reporter: Vladimir Ozerov
            Assignee: Alexander Paschenko
             Fix For: 2.3


Multiple failures are observed in concrete implementations of {{DynamicColumnsAbstractConcurrentSelfTest}}. Specifically:
{code}
testQueryConsistencyMultithreaded
testClientReconnect
testConcurrentRebalance 	
testCoordinatorChange
testConcurrentPutRemove
{code}

Apparently there are some bugs in the test itself, as the following root causes could be observed in logs:
{code}
junit.framework.AssertionFailedError: Found nodes from different clusters, probable some test does not stop nodes [allNodes=[index.DynamicColumnsConcurrentTransactionalReplicatedSelfTest3, index.DynamicColumnsConcurrentTransactionalReplicatedSelfTest2, index.DynamicColumnsConcurrentTransactionalReplicatedSelfTest1]]
{code}

{code}
Caused by: java.lang.NullPointerException: null
    at org.apache.ignite.internal.processors.cache.index.DynamicColumnsAbstractConcurrentSelfTest$3.call(DynamicColumnsAbstractConcurrentSelfTest.java:565)
    at org.apache.ignite.internal.processors.cache.index.DynamicColumnsAbstractConcurrentSelfTest$3.call(DynamicColumnsAbstractConcurrentSelfTest.java:560)
    at org.apache.ignite.testframework.GridTestThread.run(GridTestThread.java:86)
{code}
