The first put to a non-existing current directory doesn't work correctly
------------------------------------------------------------------------

                 Key: HADOOP-7803
                 URL: https://issues.apache.org/jira/browse/HADOOP-7803
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.23.0
            Reporter: Kihwal Lee


Steps to reproduce:
- Format the dfs.
- Start it.
- Put a file without specifying the destination.

$ hadoop fs -ls
ls: `.': No such file or directory

$ hadoop fs -put /etc/passwd

$ hadoop fs -ls
Found 1 items
-rw-r--r--   1 kihwal supergroup       2076 2011-11-04 10:37 .._COPYING_
{noformat}

The namenode log:
{noformat}

It ends up creating a wrong file.
