Subject [jira] Created: (HADOOP-2195) dfs mkdir command differs from POSIX standards
Date Mon, 12 Nov 2007 19:18:51 GMT
dfs mkdir command differs from POSIX standards

                 Key: HADOOP-2195
                 URL: https://issues.apache.org/jira/browse/HADOOP-2195
             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 mkdir
command. I compared the DFS output with that of RHEL 4u5:

1. mkdir a directory that exists:
Linux: mkdir: cannot create directory `test': File exists
DFS: No output

2. mkdir a directory with the name of a file that already exists:
- Linux: mkdir: `test/one' exists but is not a directory
- DFS: mkdir: java.io.IOException: Invalid directory name: <home directory>/test/one
