In order to install and configure HBase and other Hadoop ecosystem components, you must start the ZooKeeper service:
su - zookeeper -c 'source /etc/zookeeper/conf/zookeeper-env.sh ; export ZOOCFGDIR=/etc/zookeeper/conf;/usr/lib/zookeeper/bin/zkServer.sh start >> /grid/0/var/log/zookeeper/zoo.out 2>&1'
