> _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.
