> Capacity Scheduler preemption is not enabled by default in HDP. Enabling it
> affects the entire cluster and LLAP is of concern in the bug.
> *Requirement:*
> - Add a validation check about CS preemption configuration, while LLAP is not
> enabled.
> *Message:*
> {noformat}
> Enabling YARN config 'yarn.resourcemanager.scheduler.monitor.enable' is
> recommended if enabling LLAP, to ensure it is able to get cluster capacity.
> {noformat}
> If CS preemption is enabled, no validation check required.
> -> Also, uncommenting and fixing the test code in
> test_stack_advisor::test_validateHiveInteractiveSiteConfigurations().
