-----------------------------------------------
I see that the PRs are not rebased, and CircleCI is pointing to a different
dtest branch that seems identical except for the last {{@jira_ticket}} tags. I
have rebased the branches (on my repo,
[here|https://github.com/adelapena/cassandra/tree/CASSANDRA-16446-review] and
[here|https://github.com/adelapena/cassandra-dtest/tree/CASSANDRA-16446-review])
and I'm running that final CI round:

> Parent repair sessions leak may lead to node long pauses
> --------------------------------------------------------
>
> Key: CASSANDRA-16446
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16446
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Repair
> Reporter: Berenguer Blasi
> Assignee: Berenguer Blasi
> Priority: Normal
> Fix For: 4.0, 4.0-beta
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> {{ActiveRepairService}} keeps a map `parentRepairSessions`. If these
> sessions leak, that map can grow to a size when a node restarts
> {{ActiveRepairService.onRestart()}} triggers a cleanup of sessions that can
> pause nodes in a cluster for a long time.
> The proposed solution is for repairs to cleanup these sessions on all nodes
> on completion by sending a CLEANUP message to involved nodes. Tests rely on a
> new {{parentRepairSessionsCount()}} method on the parent repair sessions
> MBean to keep track of these.
