Fwd: how to perform GROUP BY:: in pig for this
Posted by Russell Jurney <ru...@gmail.com>.
I find it bad that this was so much easier for him in Hive than Pig (cross
posted question), but it looks like the datetime type and it's builtins
would fix this.

Hi Yogesh
If you are looking for the solution in hive, then the following query will
get you the required result
Select month(Date), max(rate) from date_sample Group BY month(Date);
