Like the question states, it seems as though the hadoop fs/mfs command automatically strips path down to 'HDFS version' if originally includes NFS mounting path. Would like to confirm this behavior, lest script something under false assumptions in the future.
For example, suppose that the MapR cluster is mounted via NFS at /mapr, so MFS root can be accessed at local path /mapr/clustername/. If I then enter the command
hadoop fs -ls /mapr/clusername/
it would list the root HDFS dir. just as if I had written
hadoop fs -ls /
What exactly is happening here?
