[jira] [Created] (HIVE-24116) LLAP: Provide an opportunity for preempted tasks to get better locality in next iteration

---------------------------------------

             Summary: LLAP: Provide an opportunity for preempted tasks to get better locality in next iteration
                 Key: HIVE-24116
                 URL: https://issues.apache.org/jira/browse/HIVE-24116
             Project: Hive
          Issue Type: Improvement
          Components: llap
            Reporter: Rajesh Balamohan
            Assignee: Rajesh Balamohan


In certain DAGs, tasks get preempted as higher priority tasks need to be executed. These preempted tasks are scheduled to run later, but they end up missing locality information. Ref: HIVE-24061

Remote stoarge reads can be avoided, if an opportunity is provided for these preempted to get better locality in next iteration.
