Reverted from trunk, branch-3.1 and branch-3.0. Seems branch-3.0.1 was not 
checked in so no action for 3.0.1 was taken.

> If {{KerberosAuthenticator.authenticate}} can't connect to the endpoint, you 
> get a stack trace, but without the URL it is trying to talk to.
> That is: it doesn't have any equivalent of the {{NetUtils.wrapException}} 
> handler —which can't be called here as its not in the {{hadoop-auth}} module
