Azure DataLake Gen1 python SDK for removing recursive Acl on directories

Question

I want to remove acl recursively in AzureData lake Gen1.

I can see the client APIs for Gen2.

But i can't find any client Apis for gen1.

Is it possible using python?

Below code is from Microsoft Official docs This is for DataLake Gen2

def remove_permission_recursively(is_default_scope):

    try:
        file_system_client = service_client.get_file_system_client(file_system="my-container")

        directory_client = file_system_client.get_directory_client("my-parent-directory")

        acl = 'user:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'

        if is_default_scope:
           acl = 'default:user:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'

        directory_client.remove_access_control_recursive(acl=acl)

    except Exception as e:
     print(e)

We have Python SDK to perform filesystem operations on Azure Data Lake Storage Gen1.

Here we need to install below modules:

pip install azure-mgmt-resource
pip install azure-mgmt-datalake-store
pip install azure-datalake-store

We have Microsoft documentation on this to explain about how we can handle file system operations on Azure with DLS Gen1 .

Also, we have below methods which will help us to deal with ACL:

remove_acl(self, path)
remove_acl_entries(self, path, acl_spec, recursive=False, number_of_sub_process=None)
remove_default_acl(self, path)

To use them in a recursive way we have a parameter of Boolean type where we can specify whether we can remove ACL's recursively or not.

For more details about these methods, refer to GitHub azure-datalake-store-python documentation .

Below is the function for remove_acl_entries() in detail:

def remove_acl_entries(self, path, acl_spec, recursive=False, number_of_sub_process=None):
        """
        Remove existing, named, Access Control List (ACL) entries on a file or folder.
        If the entry does not exist already it is ignored.
        Default entries cannot be removed this way, please use remove_default_acl for that.
        Unnamed entries cannot be removed in this way, please use remove_acl for that.

        Note: this is by default not recursive, and applies only to the file or folder specified.

        Parameters
        ----------
        path: str
            Location to remove the ACL entries.
        acl_spec: str
            The ACL specification to remove from the ACL at the path in the format (note that the permission portion is missing)
            '[default:]user|group|other:[entity id or UPN],[default:]user|group|other:[entity id or UPN],...'
        recursive: bool
            Specifies whether to remove ACLs recursively or not
        """
        if recursive:
            multi_processor_change_acl(adl=self, path=path, method_name="rem_acl", acl_spec=acl_spec,
                                       number_of_sub_process=number_of_sub_process)
        else:
            self._acl_call('REMOVEACLENTRIES', path, acl_spec, invalidate_cache=True)
