Description

In Oozie, we have two thread pools. One is used by SchedulerService and another is used by CallableQueueService. These are named something like pool-X-thread-Y.

Even though thread names are not logged (usually), it can still be useful in case of thread dumps and tests, where we can see where a particular XCommand is executed (see OOZIE-2564).

Suggested names:

• CallableQueueService: CallableQueue-thread-N (or just CallableQueue-N)
• Scheduler: Scheduler-thread-N (or just Scheduler-N)
