Berenguer Blasi updated CASSANDRA-16446:
----------------------------------------
Description:
{{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
{{parentRepairSessionCount()}} method on the parent repair sessions MBean to
keep track of these.
