Hi,

Thanks for your reply.
I am not sure that. How can I prove that?
Which is your dfs.tmp.dir and dfs.data.dir values?

You can check the DataNodes=B4s health with bin/slaves.sh jps | grep Datanode | sort

Which is the output of bin/hadoop dfsadmin -report?

One recomendation that I could say you is to have at least 1 NameNode and two Datanodes

regards

I checked the localhost:50070, it shows 1 live node and 0 dead node.
And =A0the log "hadoop-appuser-datanode-localhost.localdomain.log" shows= :

I have searched the related problem in the web, but i can't find a solution for helping me to solve this problem.
Anyone can give suggestion?
