-----------------------------------------------------------------------
So now whenever a new feature gets added in Tez, We can simply override that in
LlapContainerLauncher.java and do the required changes in Shuffle Handler
(LLAP) to support it.

> 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.
