删除localhost，将内容修改为

master
slave

保存退出

验证Spark安装

Spark安装正常

浏览器中访问http://master:8088/proxy/application_1480118541212_0002，可看到Spark作业界面。

[root@master spark-1.5.2-bin-hadoop2.6]# vi sbin/start-master.sh

发现

 SPARK_MASTER_WEBUI_PORT=8080

[root@master spark-1.5.2-bin-hadoop2.6]# sbin/start-master.sh

浏览器可访问master:8080，查看Spark Master
