It could very well be an environmental issue, no disagreement there. That said,
given that we've ran into this issue right away suggests that *at least* it
needs to be understood and FAQed.

(this belongs to a different thread, apologies)

I also do have a work around for it, which is, at the same time incredibly easy
and incredibly insecure -- make all users share a group with yarn.

So yes, it is possible to construct and environment that unlocks me in
KRB testing,
but I wouldn't dare run something like that in production.

If you have a production-level advise on what to do -- please chime in
on a JIRA.
