*UPDATE*
myHadoop is no longer being updated on SourceForge. For the latest, check it out on GitHub at:

myHadoop is a simple system for end-users to provision Hadoop instances on traditional supercomputing resources, without requiring any root privileges. Users may use myHadoop to configure and instantiate Hadoop on the fly via regular batch scripts.
