java - Spark 作业与 yarn-client 一起正常工作，但与 yarn-cluster 完全不工作

Question

我在用 yarn 提交 spark 作业 jar 时遇到问题。当我使用 --master yarn-client

提交它时，它运行良好并给我预期的结果

命令如下；

./spark-submit --class main.MainClass --master yarn-client --driver-memory 4g --executor-memory 4g --num-executors 4 --executor-cores 2 job.jar其他选项

但是当提交到集群模式时同样不起作用；命令如下;

./spark-submit --class main.MainClass --master yarn --deploy-mode cluster --driver-memory 4g --executor-memory 4g --num-executors 4 --executor-cores 2 job.jar 其他选项”

我的yarn-site.xml如下；

    <value>128</value>

我的 yarn 标准错误日志是

但是在完成所有操作后，我的 spark 作业没有运行，如您所见，此处未显示任何错误。这个问题背后有什么想法吗？

也许，您的从属节点不工作。你应该在命令下检查你的节点，

sudo -u yarn yarn node -list

如果找不到所有节点，则应修复节点设置。例如，关闭selinux(检查getenforce)，以及每个节点的yarn-site.xml 和core-site.xml。
