IncorrecteVersionException in installing Hadoop

Hi,

I have a problem running Hadoop on our cluster. After I formated the
namenode by executing "./bin/hadoop namenode -format", and started the dfs
by executing "./bin/start-dfs.sh", I can access the webpage of namenode at
http://localhost:50070, but the number of live data nodes is 0. If I run
"./bin/stop-dfs.sh", there are messages of "no datanode to stop" after each
ip addresses of the slave nodes listed in the /conf/slaves file. I found the
following error in the log files:

ERROR org.apache.hadoop.dfs.DataNode:
org.apache.hadoop.dfs.IncorrectVersionException: Unexpected version of
storage directory /tmp/hadoop-zhuhj/dfs/data. Reported: -11. Expecting =
-10.

However, I check the file of /tmp/hadoop-zhuhj/dfs/data/current/VERSION, it
says  "layoutVersion=-10".

I appreciate that anyone can give me some hint about what the problem is.
Thanks!

Best wishes!

This happens to me if I don't do a clean build or there is a jar somewhere on the path
containing an older hadoop version. Try "ant clean" before building and check for older releases.
Please let me know if that helps.
You may also run into a problem related to HADOOP-1212 after formatting the name-node.

Thanks,

Sorry to bother. I cleared the hadoop directory on each node, then
re-formatted it, the problem is solved.
