Code that uses Hadoop will look for mapred-site.xml, core-site.xml, hdfs-site.xml etc on your
CLASSPATH. If you add your Hadoop config directory to CLASSPATH before running the script,
Hadoop will use that configuration to connect to your cluster.

Running the word_count example the hadoop job appears to be run internally.

If I have a Cassandra cluster of 10 nodes, how does the Hadoop cluster
get configured?
