Capacity Scheduler queue via Ambari
I am facing issues while trying to introduce some of the new Capacity Scheduluer queues via Ambari, as soon as i tries to apply the changes in the Schedular YARN pops a message for RESTART but it failed to start successfully with the RESTART. I have to rollback the changes in Schedular and only afterwards YARN comes again in GREEN.
What could be the casue of that as there is no furhter information availble for this on dashboard, does yarn logs can have any information but in which section?, i did tried that successfull on Sandbox.
I am using Hadoop 18.104.22.168.0.6.0-102
