聊聊springboot 整合 hbase的问题

springboot 整合 hbase

要确定这三个端口外包可以访问
如果是127.0.0.1 可以参考修改
Linux下Hbase安装配置

<property>
<name>hbase.master.ipc.address</name>
<value>0.0.0.0</value>
</property>
<property>
<name>hbase.regionserver.ipc.address</name>
<value>0.0.0.0</value>
</property>

配置linux服务器hosts

	 vim /etc/hosts

127.0.0.1 VM-16-8-centos VM-16-8-centos
127.0.0.1  localhost.localdomain localhot
127.0.0.1  localhost6.localdomain6 localhost6
ip vm-16-8-centos  

配置window hosts

ip vm-16-8-centos
