当我运行mapreduce作业时，它从RUNNING跳转到PREP状态。我查看了mapreduce日志，但没有发现任何异常。我想知道这是否是与纱线配置有关的问题。所以，我查看了mapred-site.xml [2]的配置，看起来内存大小是正确的。尽管我已将mapreduce设置为32GB（<name>yarn.nodemanager.resource.memory-mb</name> <value>32218</value>），但我正在运行16核和64GB内存的PC。任何建议尝试调试这个？作业从RUNNING跳转到PREP状态

我不知道发生了什么事到这一点，所以我张贴在这里的部分作业的日志。我注意到作业正在运行的容器获得了CONTAINER_STOP信号。任何人都可以帮助我发生什么事情？
