-------------------------------------
Hi [[email protected]], thanks for reporting the issue here, and thanks
[~cnauroth] and [~aw] for the discussion.
I recently had an issue and reported HDFS-10211, Chris pointed out it's a
duplicate of this one. The attached patch seems for other issue. Do you mind I
work on this one?
To be backward compatible, we can add --verbose switch to fetchdt to print out
more details, but let the detail behavior to be the same as before.
For places like to one I reported in HDFS-10211, I'd like to change it to print
verbose info.
Thanks.

> HDFS {{DelegationTokenIdentifier.toString()}} adds some diagnostics info,
> owner, sequence number. But its superclass,
> {{AbstractDelegationTokenIdentifier}} contains a lot more information,
> including token issue and expiry times.
> Because {{DelegationTokenIdentifier.toString()}} doesn't include this data,
> information that is potentially useful for kerberos diagnostics is lost.
