. Failing the application.

我试着修改map,reduce端参数,如下:

set mapreduce.map.memory.mb=4096;
set mapreduce.map.java.opts=-Xmx3276M;
set mapreduce.reduce.memory.mb=4096;
set mapreduce.reduce.java.opts=-Xmx3276M;

可还是运行失败。另寻它解

解决方法如下：

关闭虚拟内存检查：即在yarn-site.xml文件添加如下配置

<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>

重启集群，终于运行出来了！！！！
