[Hadoop-common-user] [Version Mismatch between client and server] while execute "bin/hadoop -ls"

This time i checkout source from trunk and run it.
The i just came to terminal and want to see how many file there in the HDFS.
and i just execute "bin/hadoop -ls" , then error message throw out as in the
titile .

so i just have to start FSShell.java also from source code and configure
args[] time and time again.
But , without terminal , it's really uncomfortable.

is there any way to modify the *.sh file in a right way, or someone just
please update the .sh files in trunk.

Thanks
