Hi, George, Thanks. It works great.
For those who want more detail about it. You just need to add export HADOOP_USER_NAME="user" in hadoop-env.sh under you hadoop conf directory.

I put configuration files under /etc/hadoop/cluster/conf and set up env variable HADOOP_CONF_DIR=/etc/hadoop/cluster/conf However, my problem is that my ubuntu user name is different from my user name on the cluster. I tried to find where I can specify my username in the configuration files but unsuccessfully. Can anyone point me how to specify my username in the config files? Thanks. Dan
