Setting Up Access Control Lists

In CDP, HDFS supports POSIX ACLs (Access Control Lists) to assign permissions to users and groups. In lieu of Ranger policies, you use HDFS ACLs to check and make any necessary changes in HDFS permission changes.

For more information, see HDFS ACLs, Apache Software Foundation HDFS Permissions Guide, and HDFS ACL Permissions.

In Ranger, you give multiple groups and users specific permissions based on your use case. You apply permissions to a directory tree instead of dealing with individual files. For more information, see Authorizing Apache Hive Access.
