> Key: RANGER-1208
> URL: https://issues.apache.org/jira/browse/RANGER-1208
> Project: Ranger
> Issue Type: Improvement
> Components: plugins
> Affects Versions: 0.6.0, 0.6.1
> Reporter: Madhan Neethiraj
> Assignee: Abhay Kulkarni
>
> A notion of empty resource is used by plugins like Hive to check if user has
> the given access to any resource. A special case of this usage is the 'show
> databases' command in Hive, which checks if the requesting user has 'any'
> access to any resource in the system. In this case, the tag enricher should
> attempt to find if the user has been granted access via a tag associated with
> any resource in the service i.e. any database/table/column. The algorithm to
> find the tags that match for the given resource can be optimized to handle
> this special case by simply retuning all the tags associated with all
> resources in the service - eliminating the need to attempt resource matching.
