GeoIP UDF

[Johannes Rußek]

Hello Everybody,
i've been searching the web trying to find a nice to way to use GeoIP 
from pig / hadoop.
So far the only things i've been able to find is a perlscript to use 
with streaming and some suggestions to use the maxmind geoip java api 
from within hadoop (by packaging the geoip.dat file in the jar). I'd 
like to avoid streaming though.
question is, how can i access that from within pig? do i have to write a 
udf "wrapper" to use it? or can i use any function that is available in 
hadoop from pig?
Thanks,
Johannes
