That's related to this https://github.com/apache/spark/blob/master/python/pyspark/sql/functions.py#L60-L64. It's because of legacy behaviours. Yes we should convert all to `ColumnOrName`. There are some special cases where `Column` and `str` mean different things (e.g., https://github.com/apache/spark/blob/master/python/pyspark/sql/functions.py#L4795-L4796). In such cases, we should explicitly document that `str` here does not mean `Column` names. -- This is an automated message from the Apache Git Service.
