Gera Shegalov created HDFS-6143: ----------------------------------- Summary: HftpFileSystem open should through 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
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)
