Matthew Buckett commented on HADOOP-7489:
-----------------------------------------
I think the OS X JDK is trying to get some information from configd which is
failing that causes the whole LoginContent to break.
This can be worked around by specifying kerberos config on the command line:
-Djava.security.krb5.realm=OX.AC.UK
-Djava.security.krb5.kdc=kdc0.ox.ac.uk:kdc1.ox.ac.uk
> Hadoop logs errors upon startup on OS X 10.7
