Jason Brown commented on CASSANDRA-13123:
-----------------------------------------
Pushed code for cassci to run tests. I think the change to
{{CommitLogSegmentManager}} is probably legit, but I want to look at the test a
little more before +1'ing it

> Draining a node might fail to delete all inactive commitlogs
> ------------------------------------------------------------

> Key: CASSANDRA-13123
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13123
> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths
> Reporter: Jan Urbański
> Assignee: Jan Urbański
> Fix For: 3.8
>
> Attachments: 13123-2.2.8.txt, 13123-3.0.10.txt, 13123-3.9.txt,

>
> After issuing a drain command, it's possible that not all of the inactive
> commitlogs are removed.
> The drain command shuts down the CommitLog instance, which in turn shuts down
> the CommitLogSegmentManager. This has the effect of discarding any pending
> management tasks it might have, like the removal of inactive commitlogs.
> This in turn leads to an excessive amount of commitlogs being left behind
> after a drain and a lengthy recovery after a restart. With a fleet of dozens
> of nodes, each of them leaving several GB of commitlogs after a drain and
> taking up to two minutes to recover them on restart, the additional time
> required to restart the entire fleet becomes noticeable.
> This problem is not present in 3.x or trunk because of the CLSM rewrite done
> in CASSANDRA-8844.
