Description

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
