Denis Chudov updated IGNITE-21194:
----------------------------------
Description:
Test passes successully, but there are exceptions in logs.
The scenario of this test includes altering the distribution zone. But the
subsequent notification about stable assignments at the end of rebalance
happens 2 times on the same node, with the same assignments. As a result,
redundant partitions are stopped and the storages are deleted on the first
event handling, and they are not found on the second one, which causes
exceptions.
Seems that the second stable assignments change is triggered by the rebalance
raft configuration listener (
RebalanceRaftGroupEventsListener#doOnNewPeersConfigurationApplied ) which is
triggered on the configuration changed by the new leader election:
{code:java}
[2024-01-05T19:18:36,891][INFO
][%iinrt_dosor_1%rebalance-scheduler-0][RebalanceRaftGroupEventsListener] New
leader elected. Going to apply new configuration [tablePartitionId=6_part_0,
peers=[iinrt_dosor_1], learners=[]]{code}
Probably we should check that the new set of peers differs from the others to
make some rebalance related updates to meta storage.
