> [~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].
