> WebHdfsFileSystem.open and HftpFileSystem.open incorrectly handles 
> non-existing paths. 
> - 'open', does not really open anything, i.e., it does not contact the 
> server, and therefore cannot discover FileNotFound, it's deferred until next 
> read. It's counterintuitive and not how local FS or HDFS work. In POSIX you 
> get ENOENT on open. 
> [LzoInputFormat.getSplits|https://github.com/kevinweil/elephant-bird/blob/master/core/src/main/java/com/twitter/elephantbird/mapreduce/input/LzoInputFormat.java]
>  is an example of the code that's broken because of this.
> - On the server side, FileDataServlet incorrectly sends SC_BAD_REQUEST 
> instead of SC_NOT_FOUND for non-exitsing paths
