Hudson commented on HDFS-6143: ------------------------------ FAILURE: Integrated in Hadoop-Hdfs-trunk #1725 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1725/]) HDFS-6143. WebHdfsFileSystem open should throw FileNotFoundException for non-existing paths. Contributed by Gera Shegalov.

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 -- This message was sent by Atlassian JIRA (v6.2#6252)
