> {code:python}
> def drop_duplicate_columns(_rdd_df):
>     column_names = _rdd_df.columns
>     duplicate_columns = set([x for x in column_names if column_names.count(x) > 1])
>     _rdd_df = _rdd_df.drop(*duplicate_columns)
>     return _rdd_df
> {code}
> Your suggestions are appreciatd and can work on this PR, this would be my first contribution(PR)
