Description

During install I set custom pid/log folders for YARN components - /oooyarn/var/log/hadoop-yarn, /oooyarn/var/run/hadoop-yarn for RM and /ooonm/var/log/hadoop/yarn for NM.

After install, all the processes started fine and alerts are all green, etc. However the YARN service has a red-circle, showing RM as stopped. I have verified the process is up and running fine.

In the API, the RM host component has state of INSTALLED and desired state of STARTED
