Restart YARN and run a job

You must restart YARN services for all the configuration changes to take effect.

1. Restart the YARN cluster service.
2. (Optional) After you restart the YARN, you can see the new device resource count while accessing the YARN UI2 Overview and the NodeManager pages or by running the following command:
   yarn node -list -showDetails
3. Run the job requesting several nvidia.com/gpu resources:
   yarn jar <path/to/hadoop-yarn-applications-distributedshell.jar> \
