---------------------------------------------
Oops yes branch-2.6 was the broken one, it has a separate patch. I will port
only the ENOENT change to branch-2.6
thank you for confirming this.
Opened: YARN-6056 and will provide a patch there

> If a container is in the process of localizing when it is stopped/killed then
> resources are left in the DOWNLOADING state. If no other container comes
> along and requests these resources they linger around with no reference
> counts but aren't cleaned up during normal cache cleanup scans since it will
> never delete resources in the DOWNLOADING state even if their reference count
> is zero.
