Nodes with different OS Versions

Hi,

Is it possible to have nodes within the cluster running different versions of Centos?  Would this require any extra steps when upgrading?

Came across this article: https://community.cloudera.com/t5/Cloudera-Manager-Installation/How-to-do-an-OS-upgrade-on-15-nodes-...

Which appears to show how this can be done.

Re: Nodes with different OS Versions

Yes you can. You just need the parcels for both the versions. But you will face an issue when upgrading all CM agents at the same time as CM accepts one URL for upgrading the packages. You can overcome this by manually upgrading the CM Agents on the hosts that have the issue.
