This means you can now specify auth.user and still have hh use $USER as your HDFS user name.
We also now attempt to guess a reasonable auth.user if none is supplied. This is done by taking your hdfs user name, and using the same realm as the namenode principal if one exists.
In many installations this now means we don't need a .hh file even if we have Kerberos enabled.
