> Hi All,
> This is one suggestion can we have a feature in pyspark to remove duplicate columns?
> I have come up with small code for that
> {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) to Pyspark if you guys agree with it
