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.
