A great article on the emerging SMAQ stack for big data.
I wonder if PIG does spatial?

Dr. JTS and All,
I'm interested in this too. There have been some spatial Hadoop efforts. Mr. datawrangling kindly even gave us some code
https://github.com/datawrangling/spatialanalytics
to go along with this interesting presentation
http://en.oreilly.com/where2010/public/schedule/detail/12400
also interesting are

and
http://www.nathankerr.com/projects/parallel-gis-processing/gis_on_hadoop.html
However, none of these are things you could characterize as ongoing projects open to outsiders. The time is ripe for a turn-key Big Spatial Data framework!
regards,
-Frank Hardisty
