Hari Sekhon commented on YARN-3096:

That's weird, that was set by Ambari, maybe this is an Ambari issue since I 
literally just changed the number. I should have spotted this but it's been a 
few months since I was tuning Capacity Scheduler queues... doh.

I will raise this as an issue with Ambari's default in this case.

> still shows as 100% in the RM web UI under Scheduler even after doing queue
