Sure, the info server on the name node of HDFS has a read-only interface that lists directories in xml and allows the client to read files over http. There is a FileSystem implementation that provides the client side interface to the xml/http access.

To use it, you need a path with hftp as the protocol:
hadoop distcp hftp://namenode1:50070/foo/bar hdfs://namenode2:8020/foo

Very useful.  Thanks.
