Is it possible to write custom udf for group by clause in Pig

[Sanjay Bhosale]

I need to write a custom udf which will do grouping based percentage match.

Is it possible to write such custom udf?

What are the other solutions?

Hello,

IMHO you can do a filter which matches % before doing a group, despite going for a custom UDF,
