Shane Kumpf commented on YARN-9562:
-----------------------------------
Hey Eric, sorry for the delay. Just a note that my patch testing workflow is to
always start with a fresh checkout of the source, apply the patches, and start
a brand new VM, so there wasn't a switch from local to non-local.
Here is a listing of what remains after I get that exception during cleanup.

I haven't tested removing it and am out of time at the moment, but it seems
related to the private_slash_tmp dir, as that is what remains.
