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

             Summary: LocalNodeMovingPartitionsCount metrics may calculates incorrect due
to processFullPartitionUpdate
                 Key: IGNITE-9309
                 URL: https://issues.apache.org/jira/browse/IGNITE-9309
             Project: Ignite
          Issue Type: Bug
            Reporter: Maxim Muzafarov


[~qvad] have found incorrect {{LocalNodeMovingPartitionsCount}} metrics calculation on client
node {{JOIN\LEFT}}. Full issue reproducer is absent.

Probable scenario:
{code}
Repeat 10 times:
1. stop node
2. clean lfs
3. add stopped node (trigger rebalance)
4. 3 times: start 2 clients, wait for topology snapshot, close clients
5. for each cache group check JMX metrics LocalNodeMovingPartitionsCount (like waitForFinishRebalance())
{code}

Whole discussion and all configuration details can be found in comments of [IGNITE-7165|https://issues.apache.org/jira/browse/IGNITE-7165].
