[hadoop@master1 src]$ tar -xf zookeeper-3.4.12.tar -C /home/hadoop

[hadoop@master1 src]$ cd ..

[hadoop@master1 ~]$ mv zookeeper-3.4.12 zookeeper

modify environment variables

[hadoop@master1 ~]$ vi ~/.bashrc

added

export ZOOKEEPER_HOME=/home/hadoop/zookeeper

modify

export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin
