这个问题说明运行eclipse的机器没有检测到运行hbase的机器的域名,运行eclipse的机器无论是在linux还是windows中,都需要将运行hbase的ip和机器名添加到系统配置文件中。

1 如果eclipse运行在linux中,添加配置具体如下:

nano /etc/hosts

在其中添加

192.168.0.118   ubuntu118

192.168.0.186   ubuntu186

192.168.0.182   ubuntu182

2 如果eclipse运行在windows中,添加配置如下:

进入C:WINDOWSsystem32driversetc,打开其中的hosts文件,在其中加入

192.168.0.118   ubuntu118

192.168.0.186   ubuntu186

192.168.0.182   ubuntu182
