Hello, I tried adding "usern...@hostname" for eachentry in slaves file.
My slave file have 2 data nodes.it looks like below localhost utdhado...@xxx.xx.xx.229 utdhad...@xxx.xx.xx.251 error what I get when i start dfs is as below: starting namenode, logging to /home/utdhadoop1/Hadoop/hadoop-0.18.3/bin/../logs/hadoop-utdhadoop1-namenode-opencirrus-992.hpl.hp.com.out xxx.xx.xx.229: starting datanode, logging to /home/utdhadoop1/Hadoop/hadoop-0.18.3/bin/../logs/hadoop-utdhadoop1-datanode-opencirrus-992.hpl.hp.com.out *xxx.xx.xx.251: bash: line 0: cd: /home/utdhadoop1/Hadoop/hadoop-0.18.3/bin/..: No such file or directory xxx.xx.xx.251: bash: /home/utdhadoop1/Hadoop/hadoop-0.18.3/bin/hadoop-daemon.sh: No such file or directory *localhost: datanode running as process 25814. Stop it first. xxx.xx.xx.229: starting secondarynamenode, logging to /home/utdhadoop1/Hadoop/hadoop-0.18.3/bin/../logs/hadoop-utdhadoop1-secondarynamenode-opencirrus-992.hpl.hp.com.out localhost: secondarynamenode running as process 25959. Stop it first. Basically it looks for "* /home/utdhadoop1/Hadoop/** hadoop-0.18.3/bin/hadoop-**daemon.sh" but instead it should look for "/home/utdhadoop/Hadoop/...." as xxx.xx.xx.251 has username as utdhadoop* . Any inputs??
