---------------------------------------------------
Summary: BatchlogManager May Attempt to Flush Hints After
HintsService is Shutdown
Key: CASSANDRA-11062
URL: https://issues.apache.org/jira/browse/CASSANDRA-11062
Project: Cassandra
Issue Type: Bug
Reporter: Caleb William Rackliffe
Priority: Minor
Fix For: 3.0.x
{{ScheduledThreadPoolExecutor}}'s default behavior is to keep running delayed
tasks after shutdown, so I think that means {{BatchlogManager}} is trying to
call {{replayFailedBatches()}} after drain has instructed both it and the
{{HintsService}} to shut down. When this happens, we get an exception when that
tries to submit a task to the executor in {{HintsWriteExecutor}}:
