     [ https://issues.apache.org/jira/browse/SPARK-32562?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

abhijeet dada mote updated SPARK-32562:
---------------------------------------
    Description: 

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
