>          Components: Ranger
>    Affects Versions: 0.7.1
>            Reporter: Abhay Kulkarni

> 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.
