Allen Wittenauer commented on HADOOP-9520:
------------------------------------------

FWIW, I'm fully expecting to fix this bug myself like I did for our branch-1 install.  People wanted me to file bugs.  I did and got the fully expected push back that ops teams are required to hard code everything (despite this being completely unnecessary and mostly unintuitive vs ~4 code change).

> _HOST appears to ignore bound interfaces.  For example, if a host has two interfaces such that:
> nic0 = gethostname()
> nic1 = someothername
> and then I configure the namenode or resource manager to use someothername:####, the system still treats _HOST = nic0.  This is especially harmful for Kerberos principals.
