> LLAP have a dagDelete feature added as part of HIVE-9911, But now that Tez have added support for dagDelete in custom shuffle handler (TEZ-3362) we could re-use that feature in LLAP.
> There are some added advantages of using Tez's dagDelete feature rather than the current LLAP's dagDelete feature.
> 1) We can easily extend this feature to accommodate the upcoming features such as vertex and failed task attempt shuffle data clean up. Refer TEZ-3363 and TEZ-4129
> 2) It will be more easier to maintain this feature by separating it out from the Hive's code path.
