dfs ls and lsr commands differ from POSIX standards
---------------------------------------------------

                 Key: HADOOP-2190
                 URL: https://issues.apache.org/jira/browse/HADOOP-2190
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.15.1, 0.16.0
            Reporter: Mukund Madhugiri
             Fix For: 0.16.0


Assuming the dfs commands follow POSIX standards, there are some problems with the DFS ls  and lsr commands. I compared the DFS output with that of RHEL 4u5

1. ls a directory when there are no files/directories in that directory:
Linux: No output
DFS: Found 0 items

2. ls a file/directory that does not exist:
Linux: ls: /doesnotexist: No such file or directory
DFS: Found 0 items

3. lsr a directory that does not exist:
Linux: ls: /doesnotexist: No such file or directory
DFS: No output
