Answer 1

关闭防火墙，在hbase-site.xml中配置hbase.zookeeper.quorum这个属性值，把你hbase所有的节点包括master都写上去，用逗号分隔

追问

你说的那个配置 我配置了。 我第一次启动的时候 开着防火墙 后来没启动成功 我就关闭防火墙了 不过是用的service iptables stop这个暂时性的关闭命令 结果还是不行 我需不需要 把平台重启呢？因为重启还有点麻烦 所以我一直没重启平台

追答

把你的配置和集群环境 以及集群中所有节点的hosts文件贴出来看看

追问

能加下你的 Q- Q 或者不方便的话 给我个邮——箱 我发给你？在这里发 图太多了
