Review request for Ambari, Alejandro Fernandez and Sumit Mohanty.
Bugs: AMBARI-19737
https://issues.apache.org/jira/browse/AMBARI-19737
Repository: ambari
Description
-------
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:**
Enabling YARN config 'yarn.resourcemanager.scheduler.monitor.enable' is
recommended if enabling LLAP, to ensure it is able to get cluster capacity.
If CS preemption is enabled, no validation check required.
-> Also, uncommenting and fixing the test code in
test_stack_advisor::test_validateHiveInteractiveSiteConfigurations().
