I guess we're all confused as to your use case. Why do you want to run two distributed file systems on the same nodes? Why can't you use Lustre for all your needs?
As to fs.default.name, you can only have one. [That's why it is a default. *smile*] If you want to access more than one file system from within MapReduce, you'll need to specify it explicitly.
