      Description

      If a user specifies a fragment for a libjars path via generic options parser, the client crashes with a FileNotFoundException:

      java.io.FileNotFoundException: File file:/home/mapred/test.txt#testFrag.txt does not exist

      This is actually inconsistent with the behavior for files and archives. Here is a table showing the current behavior for each type of path and resource:

        Qualified path (i.e. file://home/mapred/test.txt#frag.txt) Absolute path (i.e. /home/mapred/test.txt#frag.txt) Relative path (i.e. test.txt#frag.txt)
      -libjars FileNotFound FileNotFound FileNotFound
      -files
      -archives
