-------------------------------------------
Fix Version/s: (was: 4.0-beta5)
> Parent repair sessions leak may lead to node long pauses
> --------------------------------------------------------

> Key: CASSANDRA-16446
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16446
> Project: Cassandra

> Reporter: Berenguer Blasi

> Priority: Normal
> Fix For: 4.0, 4.0-beta

> Time Spent: 0.5h

> {{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.
