Subject [jira] [Commented] (MAPREDUCE-2961) Increase the default threadpool size for container launching in the application master.

Arun C Murthy commented on MAPREDUCE-2961:
------------------------------------------

Anything above 100 threads in a overkill I think... plus each thread has a stack of 1MB. So,
we shouldn't be using too many.

We should increase that to 100 for a reasonable default, so that container launching is not
backed up by a small thread pool size.
