Start cluster zookeeper in shell script

cat start-zookeeper.sh
#!bin/sh
for node in namenode01 datanode01 datanode02
do
        echo "start zookeeper at $node"
        ssh $node "source .bash_profile;zkServer.sh start"
done

pay attention to the .bash_profile;

you should set zookeeper home variable and java_home variable

or else the start will fail.
