Upgrading the Minor Version Operating System
This topic describes the additional steps needed to upgrade the operating system of a host managed by Cloudera Manager to a higher version for minor release.
Upgrading the operating system to a higher version but within the same major release is called a minor release upgrade. For example, upgrading from Redhat 6.8 to 6.9. This is a relatively simple procedure that involves properly shutting down all the components, performing the operating system upgrade, and then restarting everything in reverse order.
This topic primarily describes all the additional steps such as backing up essential files and removing and reinstalling all the necessary Cloudera Enterprise packages and parcels.
