Hello Allen, Thanks for the reply.
You are right about trying to run two distributed filesystems. The reason being, there are certain restrictions (in our cluster environment) to include the local file system into lustre. Please tell me how would I make mapreduce access more than one file system. At least the configs don't seem to allow it.
