Description
Trying to iterate over an `HDFS(Directory(*))` object is broken because of [this line](https://github.com/blaze/odo/blob/master/odo/directory.py#L34), which uses `os.listdir` to find all the files in the directory.

Research direction
Start in odo/directory.py at line 34, where Directory iteration obtains the directory contents, and reproduce the failure with an HDFS(Directory(*)) object. Compare the directory-listing behavior available for HDFS with the current iteration path. Done means iterating over the HDFS-backed directory works and covers all entries without relying on an incompatible local-filesystem operation.
