Steve Loughran commented on YARN-4629:
--------------------------------------
presumably this problem only surfaces when the RM is listed as
{{rm@_HOST/REALM}}, which is inherently more likely in an HA env, where you
have > 1 RM. Updating the env appropriately
> Distributed shell breaks under strong security

> If the auth_to_local is set to map requests from unknown hosts to nobody, the
> dist shell app fails. The reason is that the client doesn't translate the
> _HOST placeholder to the local hostname.
