Custom partitioner

[gtruth...@gmail.com]

Following the example provided at http://dumbotics.com/2009/06/16/integration-with-java-code/#comments I've created a class MyCustomPartitioner that extends the hadoop HashPartitioner, compiled it correctly and then put it in a jar MyCustomPartitioner.jar. The problem is that I can't make hadoop find the new partitioner; running the program with:

dumbo start [python program, -hadoop, -input, -output, etc as usual] -partitioner MyCustomPartitioner -libjar MyCustomPartitioner.jar

I get the following error:

-partitioner : class not found : MyCustomPartitioner

Any suggestion? Thanks.

I'm using dumbo 0.21, (oracle) java 1.7.0_17 and hadoop 1.1.2

Is the jar on your classpath? (If you're still looking for an answer to this one. :)
