hbase外部页面无法打开，报错

打开hbase中logs日志，查看最新的

hbase-root-master-node1.out

看到如下错误信息：

解决方案：

一，打开zk安装目录，连接zk客户端，删除hbase目录

zkCli.sh -server localhost:2181

--  查看zk根目录
ls /
-- 删除hbase相关文件
rmr /hbase

重启hbase，如不生效，开始第二步操作

二，删除hdfs中 hbase目录

慎重使用，本文在本地测试环境下，没有重要数据

在 hbase-site.xml 中有配置

在页面上直接删除，重启hbase即可。
