> dfs -mv file to user home directory fails silently if the user home directory does not exist. This was working before. It will move the file if the user home directory exists.
> Here is the sequence:
> 1. bin/hadoop dfs -lsr /
> /file1 <r 3> 0 2008-03-13 19:54 rw-r--r-- hadoopqa supergroup
> 2. bin/hadoop dfs -mv /file1 file2
> 3. bin/hadoop dfs -lsr /
> /file1 <r 3> 0 2008-03-13 19:54 rw-r--r-- hadoopqa supergroup
> 4. hadoop dfs -lsr /
> /file1 <r 3> 0 2008-03-13 19:54 rw-r--r-- hadoopqa supergroup
> /user <dir> 2008-03-13 20:07 rwxr-xr-x hadoopqa supergroup
> /user/hadoopqa <dir> 2008-03-13 20:07 rwxr-xr-x hadoopqa supergroup
> /user/hadoopqa/file0 <r 3> 0 2008-03-13 20:07 rw-r--r-- hadoopqa supergroup
> 5. bin/hadoop dfs -mv /file1 file2
> 6. bin/hadoop dfs -lsr /
> /user <dir> 2008-03-13 20:07 rwxr-xr-x hadoopqa supergroup
> /user/hadoopqa <dir> 2008-03-13 20:08 rwxr-xr-x hadoopqa supergroup
> /user/hadoopqa/file0 <r 3> 0 2008-03-13 20:07 rw-r--r-- hadoopqa supergroup
> /user/hadoopqa/file2 <r 3> 0 2008-03-13 19:54 rw-r--r-- hadoopqa supergroup
> In step #2, it fails to move the file.
> In step #5, it moves the file as /user/hadoopqa directory exists.
