------------------------------------------
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}
