下载Spark版本，这版本又要求必须和jdk与hadoop版本对应。
tar -zxvf 解压到指定目录，进入conf进行培训。spark-env.sh.template 改为 spark-env.sh，注册
export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=hp01:2181,hp02:
2181,hp03:2181 -Dspark.deploy.zookeeper.dir=/spark"
JAVA_HOME也要配置，其实环境变量已经配了，如果此不配在运行sh中脚本会走这个变量，没有找到就会报 JAVA_HOME没有set的问题。上面的配置是连接zookeeper，配置问了修改slaves.template 改为slaves，添加子节点也就是worker。只需要这几步，完成以后将安装包发送到各个worker节点。启动当前的master节点。进而所有的worker都会启动起来。如果要启动另一个master节点，单独去那个节点去启动start-master.sh。通过浏览器访问两个主节点就可以看出区别。状态Status。这样也就完成了简单的一个HA搭建。

总结
刚接触spark不久如果有什么不对的地方，希望大神们对对指点。同时自己也最近一段时间，也在寻找大数据开发的工作如果有需要的可以联系本人。qq653530273,
