实现Storm的HA和Demo演示
（*）每台机器都需要修改
增加一个主节点
nimbus.seeds: ["bigdata12", "bigdata13"]
启用Event Logger 可以查看处理的数据
"topology.eventlogger.executors": 1
（*）在每个节点上启动
启动: 主节点bigdata112： storm nimbus &
UI网页 storm ui & 地址: http://ip:8080
storm logviewer & 启动日志查看器
主节点bigdata113： storm nimbus &
UI网页 storm ui & 地址: http://ip:8080
storm logviewer & 启动日志查看器
从节点bigdata113和 bigdata114： storm supervisor &
storm logviewer & 启动日志查看器
（*）Demo演示：WordCount 单词计数
