Siddharth Seth commented on TEZ-1187:
-------------------------------------
Eventually, yes - I think we should standardize the Fetchers etc to be
Callables which can use a common thread pool - provided via the context APIs.
Scheduled task execution - do we have a lot of cases for this ? Can the same
thread pool be shared, or would this end up being a separate pool.

> Thread pools are used all over for fetchers, sort etc. When running a single
> task - this is already a problem, and gets worse when running multiple tasks.
