Can not start resource manager with Fair Scheduler
Hi,
when I switched to Fair scheduler however I still can't start the Resource Manager.
I'm using CDP 7.4.4
Following steps listed here
https://community.cloudera.com/t5/Support-Questions/Unable-to-start-Node-Manager/td-p/285976
I made the following changes via UI and verified the deployed files
In yarn_site.xml
I can see from the resource manager that fair scheduler is loaded
