Steve Loughran commented on HADOOP-9421:
----------------------------------------
I'm seeing a stack trace in my code now. I'm sure it's just a simple x, but
without having to go through a large patch to work it -and for the benefit of
everyone else trying to handle these changes: how do I get my code to work again
I would recommend changing the exception string to point to a wiki entry on
this authentication -listing whatever line it is, and pointing to more details
on Hadoop security. Otherwise everyone is going to come to this JIRA once they
start searching for the error string I've pasted in.
