It looks to me like you didn't install Hadoop consistently across all nodes.
xxx.xx.xx.251: bash: > /home/utdhadoop1/Hadoop/ hadoop-0.18.3/bin/hadoop-daemon.sh: No such file or directory The above makes me suspect that xxx.xx.xx.251 has Hadoop installed differently. Can you try and locate hadoop-daemon.sh on xxx.xx.xx.251 and adjust its location properly?
