如何使用
启动zookeeper 在m1,s1,s2所有机器上执行,下面的代码是在m1上执行的示例
root@s1:/home/hadoop# /home/hadoop/zookeeper-3.4.5/bin/zkServer.sh start JMX enabled by default Using config: /home/hadoop/zookeeper-3.4.5/bin/../conf/zoo.cfg Starting zookeeper ... STARTED root@s1:/home/hadoop# /home/hadoop/zookeeper-3.4.5/bin/zkServer.sh status JMX enabled by default Using config: /home/hadoop/zookeeper-3.4.5/bin/../conf/zoo.cfg Mode: leader root@s1:/home/hadoop#
测试zookeeper是否启动成功，看下面第29行高亮处，表示成功。
