    • HDFS now supports ACLs (Access Control Lists). ACLs can specify fine-grained file permissions for specific named users or named groups.

    Description

      Currenly hdfs doesn't support Extended file ACL. In unix extended ACL can be achieved using getfacl and setfacl utilities. Is there anybody working on this feature ?
