Hi, I'm interested in developing a PERCENTILE UDF, e.g. for calculating a median, 99th percentile, 90th percentile, etc. I'd like the UDF to be parametric with respect to the percentile being requested, but I don't see any way to do that, and it seems like I might need to create PERCENTILE_50, PERCENTILE_90, etc type UDFs explicitly, versus being able to do something like GENERATE PERCENTILE(90, duration)
I'm new to Pig, so I might be missing the way to do this... is it possible? Thanks, Brian
