-------------------------------------------
Summary: Rebalancing metrics doesn't display actual information
about current rebalance state
Key: IGNITE-7449
URL: https://issues.apache.org/jira/browse/IGNITE-7449
Project: Ignite
Issue Type: Bug
Environment: In case of shutdown node with clear LFS following metrics
doesn't display correct information about rebalance:
RebalancingKeysRate
RebalancingBytesRate
KeysToRebalanceLeft
Otherwise RebalancingPartitionsCount metric displays information correctly
Steps to reproduce:
1. Cluster with enabled statistics
2. Shutdown node and clear LFS
3. Run node
4. Start node and ask node for current rebalance state through JMX:
Current result:
1 tick
RebalancingKeysRate 0
RebalancingBytesRate 0
KeysToRebalanceLeft 0
RebalancingPartitionsCount 342
2 tick
RebalancingKeysRate 0
RebalancingBytesRate 0
KeysToRebalanceLeft 0
RebalancingPartitionsCount 80
Expected:
2 tick
RebalancingKeysRate SOME_NON_ZERO_VALUE
RebalancingBytesRate SOME_NON_ZERO_VALUE
KeysToRebalanceLeft SOME_NON_ZERO_VALUE
RebalancingPartitionsCount 80
UPD: -DIGNITE_REBALANCE_STATISTICS_TIME_INTERVAL=1000 doesn't affect results
