Jian He commented on YARN-5658:
-------------------------------
Agree with Daniel here, this is a much smaller change and solves many
use-cases, as YARN today widely depends on distributed cache for app/service
deployments and a simple option to clean it up would be handy.
> YARN should have a hook to delete a path from HDFS when an application ends

> URL: https://issues.apache.org/jira/browse/YARN-5658
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Reporter: Daniel Templeton
> Assignee: Daniel Templeton
>
> There are many cases when a client uploads data to HDFS and then needs to
> subsequently clean it up, such as with the distributed cache. It would be
> helpful if YARN would do that cleanup automatically on job completion.
> The hook could be generic to an URI supported by {{FileSystem}}.
