We have jobs that require different resources and as such saturate our

What we want to do in the driver is set the number of simultaneous jobs
per node.
JobClient client = new JobClient();
Configuration configuration = new Configuration();
configuration.setInt( "mapred.tasktracker.tasks.maximum", 7);
JobConf conf = new JobConf(configuration,MergeNewSeenDriver.class);
System.err.println( "configured maximum tasks is " + conf.get(
"mapred.tasktracker.tasks.maximum" ));
But this doesn't seem to work. The only success we have had is using
multithreaded map runner, but then we don't get to run multiple reduces
at a time on the machines.
Any suggestions?
