Also, to be clear..it would work fine in Cluster mode. In Client mode,
#7394 should have taken care of the long-running app issue (though there was
one where @SaintBacchus I think mentioned that the `EventLoggingListener` was
not able to write to HDFS anymore, even though the tokens were getting updated.
So in either case, I am wondering whether in client mode, we should simply
re-login using keytab and not bother with tokens on the driver app at all (so
the AM would login, update tokens etc, while the client app always just logs
in). So you think that make sense, @tgravescs?
