Sorry for my ignorance or if I missed the answer to this question in the docs. Does HDFS NFS mount balance the load like it would for regular usage from within a hadoop cluster? It splits up the files and moves them to the node nearest to the NFS client? Or does all the NFS network traffic go through one node? Thanks for the info. Mark
