> HiveProtoLoggingHook uses a ScheduledThreadPoolExecutor to submit writer
> tasks and to periodically handle rollover. The builtin
> ScheduledThreadPoolExecutor uses a unbounded queue which cannot be replaced
> from the outside. If log events are generated at a very fast rate this queue
> can grow large.
