Note

	Note
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. For more details, see RANGER-357.
