Sumit Mohanty commented on AMBARI-10386:
----------------------------------------
The following operations fall under the category of system preparation
(sys-prepping)
* installation of package
* installation and update of repo
* user and group creation
* user and group manipulation
* uploading files and tarballs needed by services
The general idea is that only operations that are needed are configuration and
start as all other system artifacts are already available.
> Support skipping install operations on hosts that are already sys-prepped
