Haohui Mai updated HDFS-6193: ----------------------------- Priority: Major (was: Blocker) > HftpFileSystem open should throw FileNotFoundException for non-existing paths > ----------------------------------------------------------------------------- > > Key: HDFS-6193 > URL: https://issues.apache.org/jira/browse/HDFS-6193 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.4.0 > Reporter: Gera Shegalov > Assignee: Gera Shegalov > Attachments: HDFS-6193-branch-2.4.0.v01.patch, > HDFS-6193-branch-2.4.v02.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)
