I use to see Yarn Page in MCS but from past couple of days, I am seeing MapReduce Pane in MCS. Not sure whant is changed.
Can someone tell me, how to enable Yarn Pane(Switch from MapReduce to Yarn Pane) in MCS ?

Can you please try running below script once on your nodes as a root user
RAVI KUMAR GADDABATHINI - YARN statistics are visible if Resource Manager is up and running.
Is your cluster running in mixed mode / only YARN mode?
RM is running and we are running only YARN mode.
Yes. I can see nodes information in RM UI.
The only problem is in MCS, instead of Yarn pane it is displaying MapReduce Pane.
Okay, just restart RM and see if that helps...
Have you made any changes to your environment?
I have restarted RM but it didn't resolve the issue.
Change in cluster:
Moved RM from Automatic failover to Zero Configuration failover and
then reverted back to RM Automatic failover from Zero Configuration failover.
We were having issues with zero config failover hence we reverted back.
Thanks. It resolved the issue.
Calling mcs expert, Sathishkumar Manimoorthy. Please help to diagnose the issue.
