Gera Shegalov updated HDFS-6143: -------------------------------- Attachment: HDFS-6143.v05.patch I split the patch as requested. However, I hope that the fix for both hftp and webhdfs will be merged. It's pretty straightforward because they share the logic of {{ByteRangeInputStream}}. > WebHdfsFileSystem 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: Blocker > Attachments: HDFS-6143.v01.patch, HDFS-6143.v02.patch, > HDFS-6143.v03.patch, HDFS-6143.v04.patch, HDFS-6143.v04.patch, > HDFS-6143.v05.patch > > > 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 -- This message was sent by Atlassian JIRA (v6.2#6252)
