> When using pyspark.sql.functions.collect_list function in sql queries, an
> error occurs - Undefined function collect_list
> Example:
> {code}
> >>> from pyspark.sql import Row
> >>> #The same with SQLContext
> >>> from pyspark.sql import HiveContext
> >>> from pyspark.sql.functions import collect_list
> >>> sql = HiveContext(sc)
> >>> rows = [Row(age=20, job='Programmer', name='Alice'), Row(age=21,
> >>> job='Programmer', name='Bob'), Row(age=30, job='Hacker', name='Fred'),
> >>> Row(age=29, job='PM', name='Tom'), Row(age=50, job='CEO', name='Daisy')]
> >>> df = sql.createDataFrame(rows)
> >>> df.groupby(df.job).agg(df.job, collect_list(df.age))
> Traceback (most recent call last):
> File "/mnt/mfs/spark-2.0/python/pyspark/sql/utils.py", line 57, in deco
