Hi I am working on addition of adaptive behavior in Pig Execution Model. Is there any pre-defined method to estimate execution time for Pig Simple join? I think for FRJoin some method will be required to estimate it. My idea is to design an Adaptive query optimizer similar to that for Glue-Nail Deductive database system (http://portal.acm.org/citation.cfm?id=615194).
