背景
公司小组分配了三台虚拟机，在虚拟机上面意欲装hadoop集群及spark on yarn
版本
Hadoop 2.7.2
spark 2.3.2
问题
配置好hadoop集群与spark配置后，启动spark-shell --master yarn报错如下
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

有此日志可以看出由于AM的vmem内存使用(2.3G)超出了默认的(2.1G)，因此被kill掉了
解决方案
- 设置虚拟内存与物理内存比率
在yarn-site.xml中修改yarn.nodemanager.vmem-pmem-ratio(default:2.1)
<property>
<name>yarn.nodemanager.vmem-pmem-ratio</name>
<value>10</value>
</property>
- yarn.nodemanager.vmem-check-enabled，false掉
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
