If I understand correctly, to get the JobConf I have to get a MapContext... I am not sure how to get it outside of the map/reduce class, and I would like to perform initialization to the pipes application prior to running the task using HadoopPipes::runTask (outside of Map/Reduce class)... So I thought maybe I could pass on command-line parameters. If there is a way to get the JobConf outside of a Map/Reduce class, that would be nice too!
