Benoy Antony commented on HADOOP-10467:
---------------------------------------
A new configuration property - hadoop.proxyuser.<superusername>.users is added.
This accepts values of the following format : user1,user2 .
The superuser will be able to impersonate the list of users specified via this
configuration property. This is in addition to the list of groups (specified
via existing configuration property hadoop.proxyuser.<superusername>.groups)
The security documentation is also updated to reflect this new configuration.
> Enable proxyuser specification to support list of users in addition to list
> of groups.
