setting up a simple hadoop cluster with two machines, i've gotten to the point where the two machines can see each other, things seem fine, but i'm trying to set up the master as both a master and a slave, just for testing purposes.
so, i've put the master into the conf/masters file and the conf/slaves file. things seem to work, but there's no DataNode process listed with jps on the master. i'm wondering if there's a switch i need to flip to tell hadoop to use the master as a datanode even if it's in the slaves file? thanks again. -colin
