It was a bit early for me to declare my cluster is all set. The problem I'm facing is that the worker nodes are not showing up. I have a master node and three worker nodes in the cluster. "hdfs dfsadmin -report" only shows the master node. Double checked the XML files to make sure if there is any typo and they have been copied to the worker nodes correctly but found nothing. Do you have any suggestions to figure this out?
