> We have a scenario where we log in with kerberos as a certain user for some tasks, but
also want to add tokens to the resulting UGI that would be specific to each task. We don't
want to authenticate with kerberos for every task.
> I am not sure how this can be accomplished with the existing UGI interface. Perhaps some
clone method would be helpful, similar to createProxyUser minus the proxy stuff; or it could
just relogin anew from ticket cache. getUGIFromTicketCache seems like the best option in existing
code, but there doesn't appear to be a consistent way of handling ticket cache location -
the above method, that I only see called in test, is using a config setting that is not used
anywhere else, and the env variable for the location that is used in the main ticket cache
related methods is not set uniformly on all paths - therefore, trying to find the correct
ticket cache and passing it via the config setting to getUGIFromTicketCache seems even hackier
than doing the clone via reflection ;) Moreover, getUGIFromTicketCache ignores the user parameter
on the main path - it logs a warning for multiple principals and then logs in with first available.
