URL: https://issues.apache.org/jira/browse/HIVE-22514
Project: Hive
Issue Type: Bug

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.
