> The current HDFS delegation token renewal framework invokes Token.renew() and
> assumes the expiry time returned is the expiry time for the token. Further
> investigation appears to show that it is in fact the time at which the token
> should next be renewed, rather than the max time for the token. Given that,
> the current scheme may not be optimal since it will probably trigger the
> retrieval of new tokens much more often than necessary.
