> OM server is presently doing Ranger ACL check access for each path separately. This will become too costly RPC calls assume if user performs recursive delete on a path where there are millions of sub-directories under this path.
> The idea/proposal is to refine #checkAccess interface by giving "recursiveDelete" hint and make only one single call to Ranger. Also, Ranger can do an optimized approach similar to HDFS - [Reference|https://github.com/apache/ranger/blob/master/hdfs-agent/src/main/java/org/apache/ranger/authorization/hadoop/RangerHdfsAuthorizer.java#L444]
