Hi,
I guess configure is now setup(), and using toolrunner can create a configuration / context to mimic the required behavior.
Thanks,

How do we do it in the 0.20 api? I've used this in 0.19 but not sure of 0.20...

You can set these in the JobConf when you're creating the MapReduce job, and
then read them back in the configure() method of the Mapper class.
