Benoy Antony commented on HADOOP-10654:
---------------------------------------

The framework changes due to HADOOP-10679. So the customization feature needs 
to be added after HDOOP-10679. It is currently included with  HADOOP-10679. 

> Support pluggable mechanism to specify Service Authorization

> The service authorization can be specified via hadoop-policy.xml for 
> different services(protocols) using ACLS ( list of users and groups) . The 
> other subtasks will improve the standard behavior. 
> In some case, further special handling is required to restrict access based 
> on few other external characteristics of the user for special clusters. Such 
> special authorization requirements can be met if it is possible to plugin 
> authorization mechanisms at this point.
