is running 221518336B beyond the 'VIRTUAL' memory limit. Current usage: 74.0 MB of 1 GB physical memory used; 2.3 GB of 2.1 GB virtual memory used. Killing container.

在编写myjob时，报错：is running 221518336B beyond the 'VIRTUAL' memory limit. Current usage: 74.0 MB of 1 GB physical memory used; 2.3 GB of 2.1 GB virtual memory used. Killing container.
此问题原因是container在申请多余的内存时，被resouremanager杀掉了，
此处可修改hadoop/etc/mapred-site.xml
添加配置信息
<property>
　　<name>mapreduce.map.memory.mb</name>
　　<value>1536</value>
</property>
<property>
　　<name>mapreduce.map.java.opts</name>
　　<value>-Xmx1024M</value>
</property>
<property>
　　<name>mapreduce.reduce.memory.mb</name>
　　<value>3072</value>
</property>
<property>
　　<name>mapreduce.reduce.java.opts</name>
　　<value>-Xmx2560M</value>
</property>

然后重启整个haodoop模块
重新提交任务
