One is my NameNode/JobTracker + DataNode/TaskTracker and other 2 are DataNode/TaskTracker. So I have made all 3 as slave.=20 =20 In slave file I have put names of all there machines as: =20 master slave slave1 =20 When I start Hadoop cluster it always start DataNode/TaskTracker on last slave in the list and do not start DataNode/TaskTracker on other two machines. Also I got the message as: =20 slave1: : no address associated with name : no address associated with name slave1: starting datanode, logging to /home/HadoopAdmin/hadoop/bin/../logs/hadoo p-HadoopAdmin-datanode-ie11dtxpficbfise.out =20 If I change the order in slave file like this: =20 slave slave1 master =20 then DataNode/TaskTracker on master m/c starts and not on other two. =20 Please tell how I should solve this problem. =20 Sim
