 (WebHdfs|Hftp)FileSystem open should throw FileNotFoundException for 
 non-existing paths

 Key: HDFS-6143
 URL: https://issues.apache.org/jira/browse/HDFS-6143
 Project: Hadoop HDFS
  Issue Type: Bug
Affects Versions: 2.3.0
Reporter: Gera Shegalov
Assignee: Gera Shegalov
Priority: Critical
 Attachments: HDFS-6143.v01.patch, HDFS-6143.v02.patch, 
 HDFS-6143.v03.patch


 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
