Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FsShell

Hi,

I just setup 3 node hadoop cluster using the latest version from website ,
0.21.0

I am able to start all the daemons, when I run jps I see datanode, namenode,
secondary, tasktracker, but I was running a test and trying to run the
following command: ./hadoop dfs -ls, and I get the following error:

DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/fs/FsShell

Could not find the main class: org.apache.hadoop.fs.FsShell.  Program will

If i try this command instead:

./hadoop hdfs -ls
Exception in thread "main" java.lang.NoClassDefFoundError: hdfs

Does anyone know what the command really is I should be using?

Thanks
