Should i have to restart entire cluster if CM alert "Stale Confgurations"

Hi all,

The HDFS alerted that "Stale Configuration: Refresh needed" . I followed the suggestion, but i hesitated when the following image came out. I want to confirm that when i click "Restart Stale Configuration" button, the entire cluster will restart? Or only serveral servers will be restarted?

@neters Correct, this button should only restart the required services, NOT the entire cluster. The next screen should present more details before a final button to kick it off.

@neters Thank you for bringing this to our community.
Follow the onscreen instructions as mentioned by @steven-matison

Additionally, If you are concerned about the impact of restarting this service-wide/cluster-wide, We encourage you to try the rolling restart[0a]

CDH version is 5.6.12 and it is free version. So rolling restart may be not working. Thank you
