Jeff Jirsa commented on CASSANDRA-13123:
----------------------------------------
I noticed it on 3.0 branch, I haven't had time to investigate but I suspect it
may be a test ordering issue (if the two tests are run in one order they pass,
in the other they fail, so probably setup/teardown conditions).
The first failure I see in cassci (datastax's CI environment, which I don't
have access to other than the public read-only view) is
http://cassci.datastax.com/job/cassandra-3.0_testall/954/ , which is the build
after this change was committed (
http://cassci.datastax.com/job/cassandra-3.0_testall/953/ ) .
It also fails in:
http://cassci.datastax.com/job/cassandra-3.0_testall/964/
http://cassci.datastax.com/job/cassandra-3.0_testall/963/
http://cassci.datastax.com/job/cassandra-3.0_testall/956/
So % wise, it seems like 4 failures in the 15 builds since introduction.

> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths
> Reporter: Jan Urbański
> Assignee: Jan Urbański
> Fix For: 3.0.15, 3.11.1, 4.0
>

> 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.
