Session V: Hive UDAF and Partition

Hi All,

I finally found time to schedule the meetup. Let's meet next week. I am planning this to be the last session on hive. In this session we will look how to write UDAF. Another very important concept that I haven't covered in hive is Partitioning. We look at these two things.

    Hi all For tomorrow's meeting, please think about how would you write a query to determine the "mode" age for each gender group in the movielens dataset. There is no easy to write this query in hive but we can easily write a UDF or UDAF to accomplish the above task. We will go through both the approaches in tomorrow's meetup.
