Date Wed, 30 Jan 2019 15:21:00 GMT
Stepachev Maksim created IGNITE-11148:
-----------------------------------------

             Summary:  PartitionCountersNeighborcastFuture blocks partition map exchange
                 Key: IGNITE-11148
                 URL: https://issues.apache.org/jira/browse/IGNITE-11148
             Project: Ignite
          Issue Type: Bug
          Components: mvcc
            Reporter: Stepachev Maksim


We researched a problem with "execution timeout" in the Continuous Query 2 for *CacheContinuousQueryAsyncFailoverMvccTxSelfTest.testMultiThreadedFailover*.
The investigation result showed that we got MVCC problem, as result the test blocks at getAndPut,
because in some moment wrong behavior happened:

and after that:

_!IMPORTANT - we work with PartitionCountersNeighborcastFuture which doesn't provide status
information (monitoring)._

One of possible position of the problem: PartitionCountersNeighborcastFuture.onNodeLeft 

As result we have the transaction in state=PREPARED and completionTime=0 which never complete
:
