Sandy Ryza commented on YARN-1760:
----------------------------------
A couple nits:
* The same configuration is used for all the tests. If the goal is to only use
the capacity scheduler for a couple tests, then it should be instantiated in
setup()
{code}
+ configuration.set(YarnConfiguration.RM_SCHEDULER,
+
"org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler");
{code}
It looks like this goes over 80 characters. Also, probably better to use
CapacityScheduler.class.getName().
> TestRMAdminService assumes the use of CapacityScheduler
