Actually hadoop parameters could be overridden using the ToolRunner which parses the commandline and puts the hadoop conf in the Configuration object. So you can set thing like scheduler queue, mappers/system, mapred child jvm options directly from the command line. Or we can set them in the cluster configuration itself. We havent gotten around to using ToolRunner yet. I guess its high time we started doing that(not much of a work i think). It will become easier to run and tune mahout on any cluster by using the command line flags
