Sandy Ryza commented on YARN-1241:
----------------------------------
Uploaded a patch that adds the requested tests, code changes, and documentation.
bq. Not particular on it, but would be nice to move
TestCapacityScheduler#verifyConcurrentAccessOnApplications out of
TestCapacityScheduler - may be SchedulerTestUtils or something?
Definitely agree, but I think this is work for a different JIRA.
bq. Probably inconsequential, should queue.addApp be after tracking the app
below:
It needs to be the way it is because of how apps are initialized in queues.
The queue creates the AppSchedulable from the FSSchedulerApp and places it in
the FSSchedulerApp. This could maybe be cleaned up but I think this is also
work for a separate JIRA.
> In Fair Scheduler maxRunningApps does not work for non-leaf queues
