> We have a requirement to support large number of superusers. (users who impersonate as
another user) (http://hadoop.apache.org/docs/r1.2.1/Secure_Impersonation.html) 
> Currently each  superuser needs to be defined in the core-site.xml via proxyuser settings.
This will be cumbersome when there are 1000 entries.
> It seems useful to have a pluggable mechanism to specify  proxy user settings with the
current approach as the default.
