Alejandro Abdelnur commented on HADOOP-7621:
--------------------------------------------
bq. #1, keep all auth config in one place
bq. #2, make sense. Do we have such group today?
bq. #3, so where would be the location of this 'secret' file?
bq. #4, AFAIK you can set permissions with File but you cannot check them.
If we change to 'secret' file, what would be the location of this file by default?
> alfredo config should be in a file not readable by users

> [thxs ATM for point this one out]
> Alfredo configuration currently is stored in the core-site.xml file, this file is readable
by users (it must be as Configuration defaults must be loaded).
> One of Alfredo config values is a secret which is used by all nodes to sign/verify the
authentication cookie.
> A user could get hold of this secret and forge authentication cookies for other users.
> Because of this the Alfredo configuration, should be move to a user non-readable file.
