> I have built the latest 2.7, and tried S3AFileSystem.
> Then found that _mkdir_ fails on an empty bucket, named *s3a* here, as
> follows:
> {code}
> # hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -mkdir s3a://s3a/foo
> 15/03/24 03:49:35 DEBUG s3a.S3AFileSystem: Getting path status for
> s3a://s3a/foo (foo)
> 15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/foo
> 15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Getting path status for s3a://s3a/
> ()
> 15/03/24 03:49:36 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/
> mkdir: `s3a://s3a/foo': No such file or directory
> {code}
> So does _ls_.
> {code}
> # hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3a://s3a/
> 15/03/24 03:47:48 DEBUG s3a.S3AFileSystem: Getting path status for s3a://s3a/
> ()
> 15/03/24 03:47:48 DEBUG s3a.S3AFileSystem: Not Found: s3a://s3a/
> ls: `s3a://s3a/': No such file or directory
> {code}
> This is how it works via s3n.
> {code}
> # hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3n://s3n/
> # hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -mkdir s3n://s3n/foo
> # hadoop-2.7.0-SNAPSHOT/bin/hdfs dfs -ls s3n://s3n/
> Found 1 items
> drwxrwxrwx - 0 1970-01-01 00:00 s3n://s3n/foo
> {code}
> The snapshot is the following:
