Actually, their goal is the same: to analysis large volume of data based on hadoop. They both support UDF to extend its functionality. hive also support plug-in map-reduce script.
I think the biggest difference is their script languages: pig use pig-latin (maybe support sql in future) while hive use sql. To me, I prefer the pig-latin, it's more intuitive especially when script is a little long. 2009/9/8 刘祥龙 <sallonch...@hotmail.com> > Hi, everyone.
