Tom White updated MAPREDUCE-2638:
---------------------------------
Attachment: MAPREDUCE-2638.patch
Thanks for having a look Matei. The goal is to exercise the scheduler with lots
of small jobs, although in the future we could make this more complex by having
larger jobs. I managed to use the test to trigger preemption with a suitable
allocations file (described in the class javadoc).
Here's an updated patch which refactors TestFairSchedulerSystem so that the two
tests share code. I exposed properties for number of threads, jobs, pools, etc,
to make the test parameterized.
