PROBLEM
-------
I'm trying to get two peers to connect to each other.
It seems, however, that the machines are only listening on the client port?
Looking at netstat, the only port being bound is my client port (4600) and each machine is saying the connection to the other was refused.

Any ideas, help, or obvious oversights?

Trying to run a simple hadoop job, but hadoop is throwing a NoClassDef on "org/w3c/dom/Document"

I'm trying to run the basic examples from the "Mahout In Action" book (https://github.com/tdunning/MiA).

I do this using nearly the same maven setup but tooled for cassandra use rather than a file data model.

But, when I try to run the *-job.jar, it spits a NoClassDef from the datastax/hadoop end.

I'm using 1.0.5-dse of the driver as that's the only one that supports the current DSE version of Cassandra(1.2.1) if that helps at all though the issue seems to be deeper.
