　　　　　Hadoop---日志服务器

　1.历史服务器：

　　　

　　启动：

　　　　　

　　　　1）测试使用：

　　　　　　1.做一个任务：

　　　　　　　

 　　　　　2.接受任务：

　　　　　　　

　　　　　3.执行任务：　

　　　　　　　

 　　　　4.执行任务完成：

　　　　　　　

 　　　2）日志文件产生：　

　　　　　　成功后：

　　　　　　　 

　　　　　　失败后：

　　　　　　　　　　

　　　　　　点击进入History,查看日志报错

　　　3）页面：

　　　　

　　

 　　　　只能记录以java开发程序。

 2.ApplicationHistoryServer日志记录:

　　　　1）服务器搭建：

　　　　　　在yarn-site.xml中添加配置
