RE: Multiple data node and namenode ?
Hi Manish,

  Can you check how many data node processes are running really in the machine using the command 'jps' or 'ps'.

Thanks

Subject: Multiple data node and namenode ?

I am configuring cluster and starting with first machine. So i have configured the core-site, hdfs-site and mapred-site to run hadoop only on 1 machine. But somehow i am getting 2 copies of data node, namenode and secondary namenode. Not able to figure out why ?
