Karthik Kambatla commented on YARN-4805:
----------------------------------------
There is a minor chance that can happen. Previously, most of these issues were
because FairScheduler *requires* an allocation file and CapacityScheduler
doesn't. There could be other reasons this happens, but I wouldn't expect that
to be common.
> Don't go through all schedulers in ParameterizedTestBase

> ParameterizedSchedulerTestBase was created to make sure tests that were
> written with CapacityScheduler in mind don't fail when run against
> FairScheduler. Before this was introduced, tests would fail because
> FairScheduler requires an allocation file.
> However, the tests that extend it take about 10 minutes per scheduler. So,
> instead of running against both schedulers, we could setup the scheduler
> appropriately so the tests pass against both schedulers.
