cannot create file when doing dfs -put command

[Joseph Wang <jo...@yahoo.com>]

I want to setup two servers 68.14.240.166 and
68.14.240.168 to run example program. I put
the following into hadoop-site.xml and run
bin/start-all.sh on both nodes. However,
when I try to run
   "bin/hadoop dfs -put input input"
to copy file into ndfs, I get an error
stating it cannot create file. I looked
under /tmp/hadoop/dfs. There is no
/tmp/hadoop/dfs/data. The directory is
read & writable by anyone. Any suggestion?
