In order to access HDFS folders in previous versions of HDP, access permissions also had to be granted in Ranger to the applicable parent folders. As of HDP-2.3, it is no longer required to grant access permissions to the parent folder.

For example, for the folder path ../customer/data/marketing:

  • In previous versions, to grant access to the /customer/data/marketing folder, you were required to grant Execute permission in Ranger for both the /customer and /customer/data folders, along with a Read or Write permission for the /customer/data/marketing folder.

  • As of HDP-2.3, it is no longer necessary to grant Execute permission to the parent folders.
