Hi, All I need to setup a hadoop/hdfs cluster with one namenode on a machine and two datanodes on two other machines. But after setting datanode machiines in conf/slaves file, running bin/start-dfs.sh can not start hdfs normally.. I am aware that I have not specify the root directory hadoop is installed on slave nodes and the OS user account to use hadoop on slave node. I am asking how to specify where hadoop/hdfs is locally installed on slave node? Also how to specify the user account to start hdfs there?
Regards, Richard
