I am planning to do an automation where i can do OS upgrade/patching (One node at a time) which needs node restart. How can i test the services are up and running on that node after patching ? Looking for something like api which can help to validate services on datanode,namenode and edge node.

Thanks for sharing the detailed information and will try to update the spark-env to use default mode as yarn.

Facing issue where users are starting spark session in local mode and not the yarn mode. So need to identify users and update them on the process how they can start using yarn mode to avoid load on local node. Is there any document available on best practice for spark, which can help to educate users on the best ways to work on spark and how to launch spark session ?

I am able to list jobs using below command with different status as finished/failed/killed. http://hostname:8088/ws/v1/cluster/apps?states=FINISHED but what i need is, the report should list jobs for a week or month ? I need to list finished jobs for a month and then list jobs for a week?
