Inconsistency of filehandler which causes TypeError: ArrowHandler.is_legal() missing 1 required positional argument: 'filepath'

• We encountered below error:

[rank1]:     if self.filehandler.is_legal(os.path.join(root, name))
[rank1]:        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[rank1]: TypeError: ArrowHandler.is_legal() missing 1 required positional argument: 'filepath'

• The root cause seems to be at this line which is NOT a class instance. So the simple fix is to add bracket at the end like this:

        filehandler = _handler_map[cfg.file_type]()
