Aaron T. Myers updated HADOOP-11158:
------------------------------------
    Attachment: HADOOP-11158.patch

Trivial patch attached. No tests are included since the fix is so obvious. I tested this manually
on a cluster exhibiting this problem and confirmed that it works as expected.

> The {{KerberosAuthenticationHandler}} currently defines no default value for the "{{.kerberos.name.rules}}"
config key, which means that users who use this class and don't set this setting will get
an NPE. We should set the default for this "DEFAULT" like it is for the other Kerberos name
mapping properties in Hadoop.
