[jira] [Created] (IGNITE-7898) IgniteCachePartitionLossPolicySelfTest is flaky on TC

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

             Summary: IgniteCachePartitionLossPolicySelfTest is flaky on TC
                 Key: IGNITE-7898
                 URL: https://issues.apache.org/jira/browse/IGNITE-7898
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.4
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko


Affected tests:
testReadOnlyAll
testReadWriteSafe

Exception:
{code:java}
junit.framework.AssertionFailedError: Failed to find expected lost partition [exp=0, lost=[]]
    at org.apache.ignite.internal.processors.cache.distributed.IgniteCachePartitionLossPolicySelfTest.verifyCacheOps(IgniteCachePartitionLossPolicySelfTest.java:219)
    at org.apache.ignite.internal.processors.cache.distributed.IgniteCachePartitionLossPolicySelfTest.checkLostPartition(IgniteCachePartitionLossPolicySelfTest.java:166)
    at org.apache.ignite.internal.processors.cache.distributed.IgniteCachePartitionLossPolicySelfTest.testReadWriteSafe(IgniteCachePartitionLossPolicySelfTest.java:114)
{code}

The problem of failure:
After we prepare topology and shutdown the node containing lost partition we start to check it immediately on all nodes (cache.lostPartitions() method). Sometimes we invoke this method on client node where last PME is not even started and getting empty list of lost partitions because we haven't received it yet on PME.

Possible solution:
Wait for PME finishing on all nodes (including client) before start to check for lost partitions.
