The department currently has a small, somewhat limited Hadoop cluster available for department users. Resource sharing is not mediated by PBS or any other kind of resource scheduling system so please be aware of other users and please clean up your work.
The hadoop package currently installed in /opt/hadoop-2.4.1/
The preferred Java (and set as your $JAVA_HOME) is Sun 1.7 in /opt/java:
