java.net.ConnectException: Connection refused解决：
1.查看监听的端口
[hadoop@master logs]$ netstat -an |grep 2181
tcp 0 0 0.0.0.0:2181 0.0.0.0:* LISTEN
不知道为什么一开始监听在IPV6地址上，后来我给禁止IPV6，（google说是bug）。
2. 删除之前hbase 在hadoop上的源数据
[hadoop@master logs]$ hadoop fs -rm -R -f /hbase
3. 重新配置，并且分发给其他节点
这个问题很奇怪，不能重现，删除了、hbase 很可能再也重新启动时，都会报链接不了master，拒接链接，这时重启hadoop，重启hbase。
因为报错，反复修改了很多次配置，重装了很多次，最后次都是玩去删除，直接重新配置分发的。 这个虽然这个问题解决了，但是没有get 具体原因。
先记录下此次解决的新路历程吧。也有人说是ntp 感觉没关系，时间一样的
