Using Numpy and SciPy on Apache Pig
You can stream through a (C)Python script that imports scipy.
I am for instance using this to cluster data inside bags, using import scipy.cluster.hierarchy
I want to write UDFs in Apache Pig. I'll be using Python UDFs. 
My issue is I have tons of data to analyse and need packages like NumPy and SciPy. Buy this they dont have Jython support I cant use them along with Pig. 
Do we have a substitue ?
