Dear Sirs/madams

i am trying to run hadoop 1.0.4 in the pseudo distributed mode, but i am
facing with

datanode log,

01/05/2013 13:16:54 2013-05-01 13:16:54,206 ERROR
org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException:
Incompatible namespaceIDs in /home/mohs/hadoop/dfsdirdata: namenode
namespaceID = 717658700; datanode namespaceID = 1318489331


job-tracker log:

01/05/2013 13:24:40 org.apache.hadoop.ipc.RemoteException:
java.io.IOException: File /home/mohs/hadoop/tmp/mapred/system/
jobtracker.info could only be replicated to 0 nodes, instead of 1

data-node log:
01/05/2013 13:26:10 2013-05-01 13:26:09,711 WARN
org.apache.hadoop.hdfs.DFSClient: DataStreamer Exception:
org.apache.hadoop.ipc.RemoteException: java.io.IOException: File
/home/mohs/hadoop/tmp/mapred/system/jobtracker.info could only be
replicated to 0 nodes, instead of 1

i have tried to solve this by removing the files in /tmp/hadoop/* and
running hadoop namenode -format

but i am facing with the same error.
do you have any solution for this?

regards
Mohsen
