java - Hadoop 映射器因 "Container killed by the ApplicationMaster"而失败

Question

我正在尝试在 Hadoop 上执行 map reduce 程序。

当我将作业提交到 hadoop 单节点集群时。正在创建作业，但失败并显示消息

“容器被 ApplicationMaster 杀死”

使用的输入大小为 10 MB。

当我使用输入文件 400 KB 的相同脚本时，它成功了。但是对于大小为 10 MB 的输入文件失败。

我的终端显示的完整日志如下。

我这里的映射器正在触发另一个程序，它将在这里处理我的输入文件。被映射器触发的程序通常会消耗大量内存。

所以请在这方面帮助我。

在 yarn-site.xml 中包含以下属性并重启 VM，

<property>
   <name>yarn.nodemanager.vmem-check-enabled</name>
   <value>false</value>
   <description>Whether virtual memory limits will be enforced for containers</description>
</property>

<property>
   <name>yarn.nodemanager.vmem-pmem-ratio</name>
   <value>4</value>
   <description>Ratio between virtual memory to physical memory when setting memory limits for containers</description>
</property>
