Question

我在独立模式下在Ubuntu 16.04上设置了hadoop 2.7.3。我已经安装了Hive 2.1.1并且正在使用HQL。大多数查询会触发MR作业。当我运行触发MR作业的查询时，系统会通过终止所有进程自动注销。当我检查节点管理器的日志时，我可以看到导致问题的声明是

WARN org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor: Exit code from container container_1494943588964_0010_01_000001 is : 143
2017-05-16 19:48:08,263 ERROR org.apache.hadoop.yarn.server.nodemanager.NodeManager: RECEIVED SIGNAL 15: SIGTERM
2017-05-16 19:48:08,297 WARN org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor: Exit code from container container_1494943588964_0010_01_000002 is : 143
2017-05-16 19:48:08,304 INFO org.apache.hadoop.yarn.server.nodemanager.containermanager.container.ContainerImpl: Container container_1494943588964_0010_01_000001 transitioned from RUNNING to EXITED_WITH_FAILURE

通常，日志文件包含语句：

RECEIVED SIGNAL 15: SIGTERM

请找到yarn-site.xml中设置的属性：

yarn.nodemanager.aux-services = mapreduce_shuffle
yarn.nodemanager.resource.memory-mb = 6144
yarn.scheduler.minimum-allocation-mb = 2048
yarn.scheduler.maximum-allocation-mb = 6144 
yarn.app.mapreduce.am.resource.mb = 1024
yarn.app.mapreduce.am.command-opts = -Xmx819m

任何人都可以帮忙..

收到的信号15：信号可能是由于多种原因造成的，用户可能会杀死该应用程序，或者容器可能会达到其容量资源。

WARN org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor：容器container_1494943588964_0010_01_000001的退出代码是：143
