How to handle/plan OS patching (with reboot) of 1000 node CDH cluster

[#1]

Hi team,

Suppose we have a 1000-node CDH cluster and our system admin team wants to perform an OS patching on these 1000 servers which will involve the reboot of the nodes also.

So, how should I plan/handle this task with minimum or no impact on the application teams' tasks who are using this CDH cluster? What are the best practices I have to keep in mind for handling this activity?
