Yep that was it. I changed the method signature to LongWriteable for
the 1st parameter (also annotated it w/ Override to see the compile

Bharath,
The mapred package is largely deprecated, as hadoop is moving towards the
mapreduce package. Use mapreduce for any new jobs you write, because mapred
will go away in some future release. For now, both are there to give
developers time to rewrite existing older jobs.

I have done basic spatial joins intersecting 100s millions of points
with 100s thousands of polygons but this is all. It's something I'd

If you're working with the Cloudera distribution, you can install CDH1
(0.18.3) and CDH2 (0.20.1) side-by-side on your development machine.
They'll install to /usr/lib/hadoop-0.18 and /usr/lib/hadoop-0.20; use
/usr/bin/hadoop-0.18 and /usr/bin/hadoop-0.20 to execute, etc.
