> {{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}}:
> {noformat}
