Sandy Ryza commented on YARN-1760:
----------------------------------
I assume that YARN-1679 will have
"conf.setClass(YarnConfiguration.RM_SCHEDULER_CLASS, FairScheduler.class)" in
the FS-specific tests that it adds. This JIRA adds the same to the CS-specific
tests. In some other JIRAs, I've tried to make it so that certain tests pass
independent of whether the Fair or Capacity scheduler is used. But the goal
with this patch is just to make the dependency of the existing tests on the
Capacity Scheduler explicit so that it will override a non-CS default.
