S3 Access from Hadoop

This command works on previous versions of Apache Hadoop.

hadoop fs -conf /tmp/test.xml -ls s3n://mybucket/

In CDH4 Beta2, it gives me this:

Found 63 items
-ls: -0s
Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]

Contents of test.xml:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
