>                 URL: https://issues.apache.org/jira/browse/HADOOP-13611
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs, fs/s3
>    Affects Versions: 2.7.3
>            Reporter: Steve Loughran
>            Priority: Trivial
>
> If you look at {{FileSystem.processDeleteOnExit()}}, it does an exists() check for each entry, before calling delete().
> That exists() check is superfluous; on s3 it add an extra 1-4 HTTP GETs
> This could be fixed with a subclass in s3a to avoid it, but as the call is superfluous in *all* filesystems, it could be removed in {{FileSystem}} and so picked up by all object stores.
