图文+代码讲解spark-2.1.0集群搭建

集群如下：

192.168.188.111 master

192.168.188.112 slave1

192.168.188.113 slave2

1 .修改主机名及域名解析

    1.1 修改主机名

[root@master ~]# vim /etc/hostname

    输入master

     同理在192.168.188.112和192.168.188.113分别修改为slave1和slave2.

    1.2 修改域名hosts

[root@master ~]# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.188.111 master
192.168.188.112 slave1
192.168.188.113 slave2

2.配置spark-2.1.0
