------------------------------------
Summary: Add test to verify node stop does not hang when
MetaStorage is unavailable
Key: IGNITE-25281
URL: https://issues.apache.org/jira/browse/IGNITE-25281
Project: Ignite
Issue Type: Bug
Reporter: Mirza Aliev
h3. Motivation
We need to add a test that ensures a node can be stopped cleanly even when
MetaStorage is unavailable.
This issue was observed in a scenario where doStableKeySwitch holds the
TableManager's busyLock, preventing {{beforeNodeStop}} from completing.
Additionally, a {{TimeoutException}} is thrown inside {{doStableKeySwitch}}
when calling {{metaStorageMgr.invoke(...).get()}}, because the only MetaStorage
node is already stopped. This exception currently leads to a call to the
FailureHandler. However we have agreed to not call FH in the case of
{{TimeoutException}} in the ticket
https://issues.apache.org/jira/browse/IGNITE-25278. Also we have agreed to add
recovery mechanism for stable switch intents after MetaStorage becomes
available in https://issues.apache.org/jira/browse/IGNITE-25276
The test should reproduce general situation when MetaStorage become
unavailable and confirm that the stop process completes gracefully without
hanging, even if MetaStorage is down.
