Description

qvad have found incorrect LocalNodeMovingPartitionsCount metrics calculation on client node JOIN\LEFT. Full issue reproducer is absent.

Probable scenario:

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())

Whole discussion and all configuration details can be found in comments of IGNITE-7165.
