             Summary: Ozone-Ranger integration : Recursive ACL check for subpaths
                 Key: HDDS-4593
                 URL: https://issues.apache.org/jira/browse/HDDS-4593
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Rakesh Radhakrishnan


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]

 
{code:java}
RangerOzoneAuthorizer#checkAccess(IOzoneObj ozoneObject, RequestContext context)

public class RequestContext {
     …...
     private final boolean recursiveDelete; // add new attribute
}
{code}
