> 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
> Assignee: Ke-Yi Sung
> Priority: Major
>
> 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]
