AttributeError: 'Column' object has no attribute 'replace'
So in fact I need somehow to get the value of the column df.str in
order to call replace on it.
Any ideas how to do this?

Hello,
I am using following transformations on RDD:
rddAgg = df.map(lambda l: (Row(a = l.a, b= l.b, c = l.c), l))\
.aggregateByKey([], lambda accumulatorList, value:
accumulatorList + [value], lambda list1, list2: [list1] + [list2])
I want to use the dataframe groupBy + agg transforma
