Alexey Platonov created IGNITE-9531:
---------------------------------------
Summary: ZookeeperDiscovery testClientReconnect is flaky in master
Key: IGNITE-9531
URL: https://issues.apache.org/jira/browse/IGNITE-9531
Project: Ignite
Issue Type: Bug
Reporter: Alexey Platonov
Assignee: Alexey Platonov
Fix For: 2.8
The test IgniteClientReconnectCacheTest#testReconnectMultinode(LongHistory)
periodically fails with timeouts in master.
>From the logs I see that the hang is caused by one of the two assertion errors:

The test failure can be rarely reproduced locally (run repeatedly with CPU
stress enabled).
