> 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]]
