> Ranger authorizer plugin for HDFS, when asked to authorize certain accesses,
> requires to check if the user is authorized to do more than one permission
> for the requested resource. Currently, this is achieved by the plugin making
> separate call into Ranger policy engine to check authorization for each such
> permission. This works, but is inefficient.
> A recent improvement in Ranger policy engine (RANGER-3999) adds support for
> specifying multiple permissions that need to be authorized for a resource in
> one Policy engine call. This Jira updates the Ranger plugin for HDFS to use
> this feature, thereby improving performance of access authorization for
> certain access requests.
