eclipse远程hbase 无法连接 org.apache.hadoop.hbase.MasterNotRunningException

1、问题描述：使用eclipse通过hbase api访问hbase错，实验环境为eclipse安装在windows10下，hbase安装在虚拟机CentOS7下，其中Centos7
hbase IP地址为192.168.137.11  org.apache.hadoop.hbase.MasterNotRunningException

2、分析思路：1）通过jps查看Hbase Hregionserver都已经启动了,排除没启动原因

2）查看/etc/hosts 发现 127.0.0.1 对应的域名为localhost 已经注释掉了，排除域名解析原因。

#127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

#::1         localhost localhost.localdomain localhost6 localhost6.localdomain6


192.168.137.11  bigdata

 3）然后查看Hbase和Hregionserver日志（hbase/logs下）发现regionserver日志监听地址为127.0.0.1定位了出错原因：这里是192.168.137.11
对应的域名 bigdata 才正确






       



3、解决方案：CentOS7 图形界面设置IP时勾选了 如下图红圈所示：

这会是hbase启动时读取IP时，会使用127.0.0.1作为regisionserver的监听地址。因此使用CENTOS7 图形界面配置网络上一定不要改选此项。
