So, I'm pretty sure (now) that it DOESN'T work. There are comments here: http://answers.mapr.com/questions/9224/apache-hadoop-client-connecting-to-namenode.html and here: http://doc.mapr.com/display/MapR/Accessing+MapR-FS+in+Java+Applications plus the connector here: https://github.com/pentaho/pentaho-hdfs-vfs that all point to special MapR code being needed, and the standard HDFS client protocols not working. Plus all my testing seemed to confirm this.
We have figured out a workaround for our configuration, though (we're basically requiring an NFS mount of the MapR file system, so we can just browse the MapR files as native).

I've not seen VFS used in this configuration before. You could try updating to the current HDFS jar files.

Hi all, I'm using Commons VFS 2.1 along with the HDFS connector and everything is working brilliantly ... until, that is, trying to access HDFS on a MapR system. Then I get things like null host name exceptions and the like. So, anyone have any idea whether the HDFS connector even COULD work against MapR? And if not, anyone tried to build a MapR connector to Commons VFS 2.1? Thanks in advance, ~Roger Whitcomb
