Vinod Kumar Vavilapalli commented on YARN-707:
----------------------------------------------
I did change that, the owner of the token IS the user now in the patch and App
attempt is an additional field.
Re real/effective user, for these tokens, essentially they are the same, and
correspond to the app-submitter.
We can make other enhancements according to your suggestions if you have any in
a follow up.
Jason, if you are okay with the patch, can you please commit it? Thanks.
