---------------------------------------------------
Summary: The user must be clearly communicated about YARN
pre-emption requirements when Hive LLAP is enabled
Key: AMBARI-19859
URL: https://issues.apache.org/jira/browse/AMBARI-19859
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.5.0
Reporter: Vivek Ratnavel Subramanian
Assignee: Vivek Ratnavel Subramanian
Fix For: 2.5.0
Capacity Scheduler preemption is not enabled by default in HDP. Enabling it
affects the entire cluster. But it is strongly recommended to enable YARN
pre-emption before enabling Hive LLAP. The user needs to be warned about this
before enabling Interactive Query in Hive configs page.
