Robert Joseph Evans updated HDFS-2785:
--------------------------------------

    Attachment: HDFS-2785.txt

There are no tests included with this patch, because in reality none of the 
real functionality should have changed.  There were just 3 things modified.

# The URI returned by getUri is no longer based off of the INetAddress for the 
NameNode.  This is because the host is resolved in the INetAddress and not in 
the origninal URI.
# The code to get the INetAddress from a token goes directly to security Utils 
and not through NetUtils.  This is to make the token more opaque as it was 
originally designed to be.
# The TGT renewal no longer checks for expirey of the TGT.  This change is only 
to make it consistent with HFTP, and is not truly needed.  It can be removed if 
reviewers want it to be removed.

> Need to port 205 tokens into these filesystems.  Will mainly involve ensuring
