spark2.1出来了，想玩玩就搭了个原生的apache集群，但在standalone模式下没有任何问题，基于apache hadoop 2.7.3使用spark on yarn一直报这个错。(Java 8)
报错日志如下：

解决方案：
修改yarn-site.xml，添加下列property
<property> <name>yarn.nodemanager.pmem-check-enabled</name> <value>false</value> </property> <property> <name>yarn.nodemanager.vmem-check-enabled</name> <value>false</value> </property>
分析：
按照上述配置提供的信息，目测是我给节点分配的内存太小，yarn直接kill掉了进程，导致ClosedChannelException
文献参考：http://stackoverflow.com/questions/38988941/running-yarn-with-spark-not-working-with-java-8
实测：不修改yarn-site.xml，换成Java 7可正常执行。
