Mikhail Petrov created IGNITE-27911:
---------------------------------------

             Summary: Fix flaky ContinuousQueryBuffersCleanupTest
                 Key: IGNITE-27911
                 URL: https://issues.apache.org/jira/browse/IGNITE-27911
             Project: Ignite
          Issue Type: Task
            Reporter: Mikhail Petrov


ContinuousQueryBuffersCleanupTest.testContinuousQueryBuffersCleanup is flaky 

https://ci2.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=7027898245839601671&tab=testDetails

ContinuousQueryBuffersCleanupTest.testBackupUpdateAndBackupContinuusQueryAcknowledgmentReordered is flaky

https://ci2.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=123031614678612627&tab=testDetails

The reason of failures is usage of

{code:java}
new RendezvousAffinityFunction().setPartitions(2)
{code}

The RendezvousAffinityFunction has a chance of mapping both partitions to the same node. But mentioned tests require each partition to be mapped to a separate node.

It can be easily reproduce by modification of RendezvousAffinityFunction.
