---------------------------------------

             Summary: Flaky test SystemViewSelfTest.testContinuousQuery.
                 Key: IGNITE-12925
                 URL: https://issues.apache.org/jira/browse/IGNITE-12925
             Project: Ignite
          Issue Type: Test
            Reporter: Mikhail Petrov


It is needed to fix SystemViewSelfTest.testContinuousQuery test, which is flaky – [TC history|https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=2075278944640125900&tab=testDetails&branch_IgniteTests24Java8=pull%2F7696%2Fhead].

It seems that QueryCursor#close method 
 gives no guarantees that CQ routine will be cleared from all nodes before its returning. This behavior is due to StopRoutineDiscoveryMessage is immutable and so StopRoutineAckDiscoveryMessage can be received (QueryCoursor#close method returns) before GridContinuousProcessor#processStopRequest completion on all nodes.
