> Key: RANGER-1695
> URL: https://issues.apache.org/jira/browse/RANGER-1695
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 0.7.1
> Reporter: Abhay Kulkarni
> Assignee: Abhay Kulkarni
> Fix For: master
>
>
> HDFS commands such as getContentSummary and delete require Ranger to
> authorize access to entire directory hierarchy rooted at the directory passed
> in as argument. Ranger could optimize this code by pruning the directory tree
> whenever a sub-directory, and directory hierarchy rooted in it, is authorized
> for requested access. This could potentially save many spurious authorization
> API calls with Ranger policy engine.
> Also, it will be useful to gather and log performance metrics for the Ranger
> authorization API call for every Ranger plugin.
