Mridul, Something that is lost on many people. You do NOT need SSH keys are the scripts start-all stop-all to start hadoop or hbase. That is only one suggested way.
cd $hadoop_home bin/hadoop-daemon.sh start namenode bin/hadoop-daemon.sh start datanode bin/hadoop-daemon.sh start jobtracker bin/hadoop-daemon.sh start tasktracker This should be more clear in the docs, one would think hadoop/hbase works over ssh keys when infact the keys do nothing but start deamons and the start_all scripts are just loop constructs.
