我们通常可以在“/var/log/hadoop yarn/containers”路径中看到yarn容器日志。虽然我能够看到成功作业的日志，但无法看到失败作业的日志。节点管理器日志显示正在删除的日志。
日志：

2017-07-13 14:16:04,170 INFO org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor (DeletionService #1): Deleting path : /var/log/hadoop-yarn/containers/application_1234567890_12345/container_11234567890_12345_11_0000

下面是我的yarn-site.xml的一个片段。
有人能告诉我需要修改什么配置来保留失败作业的日志吗？
