Description

The Native S3 file system cannot list paths from the root.

NativeS3FileSystem.listStatus("/") throws IllegalArgumentException in both Hadoop 1.0.4 and 1.1.1:

java.lang.IllegalArgumentException: Can not create a Path from an empty
string
	at org.apache.hadoop.fs.Path.checkPathArg(Path.java:82)
	at org.apache.hadoop.fs.Path.<init>(Path.java:90)
	at org.apache.hadoop.fs.Path.<init>(Path.java:50)
	at 
org.apache.hadoop.fs.s3native.NativeS3FileSystem.listStatus(NativeS3FileSy
stem.java:437)

where the fs.default.name is any of s3n://bucket/, s3n://bucket ,
s3n://bucket/foder or s3n://bucket/folder/

I tried all file-system variants (just the bucket, w/ and w/o trailing
slash, bucket + folder, w/ or w/o trailing slash).
