> There is an example on [Hive Getting Started|https://cwiki.apache.org/confluence/display/Hive/GettingStarted] page using the MovieLens100k dataset. The mapper is defined as a python script in the following way:
> {code}
> import sys
> import datetime
> for line in sys.stdin:
>   line = line.strip()
>   userid, movieid, rating, unixtime = line.split('\t')
>   weekday = datetime.datetime.fromtimestamp(float(unixtime)).isoweekday()
>   print '\t'.join([userid, movieid, rating, str(weekday)])
> {code}
> which is correct assuming you're using the python 2 series. The following code works with both 2 and 3 series:
> {code}
> from __future__ import print_function
> import sys
> import datetime
> for line in sys.stdin:
>   line = line.strip()
>   userid, movieid, rating, unixtime = line.split('\t')
>   weekday = datetime.datetime.fromtimestamp(float(unixtime)).isoweekday()
>   print('\t'.join([userid, movieid, rating, str(weekday)]))
> {code}
> I think this should be corrected.
