Doug,
I may be wrong, but last time I tried (on 0.12.3), MapRed didn't work
for non-default filesystem as an input.
(output worked fine.)
https://issues.apache.org/jira/browse/HADOOP-71
https://issues.apache.org/jira/browse/HADOOP-1107
Mine failed with "org.apache.hadoop.mapred.InvalidInputException: Input
path does not exist".
It basically checked the default file system instead of the one passed in.

But inputs don't have to be in the default filesystem nor must they be
in HDFS. They need to be in a filesystem that's available to all
nodes. They could be in NFS, S3, or Ceph instead of HDFS. They could
even be in a non-default HDFS system.
