Branimir Lambov commented on CASSANDRA-8992:
--------------------------------------------
Patch up for review
[here|https://github.com/apache/cassandra/compare/trunk...blambov:8992-commitlogtest].
The storage service shutdown hook will hang indefinitely if flushes cannot
complete for whatever reason. Test timeout does not help as it the hook (at
least on Linux) is being run post-timeout.
I found two different reasons for this happening in CommitLogTest:
- compaction needing commit log while it is being reset unsafely
- commit failure policy tests followed by later truncate test
The patch fixes the two problems above, the test appears to have stopped
hanging locally for me. I'm not sure if it is a good idea to introduce a
timeout on the flushes in the shutdown hook, so I left that unchanged.
