Diagnostics: Container is running beyond virtual memory limits 运行Tez时检查到用过多内存而被NodeManager杀死进程问题：_综合

1）运行Tez时检查到用过多内存而被NodeManager杀死进程问题：

Caused by: org.apache.tez.dag.api.SessionNotRunning: TezSession has already shutdown. Application application_1546781144082_0005 failed 2 times due to AM Container for appattempt_1546781144082_0005_000002 exited with exitCode: -103
For more detailed output, check application tracking page:http://hadoop103:8088/cluster/app/application_1546781144082_0005Then, click on links to logs of each attempt.
Diagnostics: Container [pid=11116,containerID=container_1546781144082_0005_02_000001] is running beyond virtual memory limits. Current usage: 216.3 MB of 1 GB physical memory used; 2.6 GB of 2.1 GB virtual memory used. Killing container.

这种问题是从机上运行的Container试图使用过多的内存，而被NodeManager kill掉了。
在这里插入图片描述

解决方法：
关掉虚拟内存检查，修改yarn-site.xml，修改后一定要分发，并重新启动hadoop集群。

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