             Summary: LLAP node specific preemption will only preempt once on a node per AM
                 Key: HIVE-14403
                 URL: https://issues.apache.org/jira/browse/HIVE-14403
             Project: Hive
          Issue Type: Bug
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


Query hang reported by [~cartershanklin]

Turns out that once an AM has preempted a task on a node for locality, it will not be able to preempt another task on the same node (specifically for local requests)

Manifests as a query hanging. It's possible for a previous query to interfere with a subsequent query since the AM is shared.
