> 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.
