我正在以集群模式在独立的测试Spark上运行作业，但是我发现自己无法监视驱动程序的状态。
这是一个使用spark-2.4.3的最小示例（主节点和一个工作节点在同一个节点上运行，并开始使用默认的conf在freshly unarchived installation上运行sbin/start-all.sh，不使用conf/slaves设置），从节点本身执行spark-submit：
> spark-submit --master spark://ip-172-31-15-245:7077 --deploy-mode cluster \
--class org.apache.spark.examples.SparkPi \
/home/ubuntu/spark/examples/jars/spark-examples_2.11-2.4.3.jar 100

Spark状况良好（我可以执行上述工作之后执行其他作业）， driver-20190627090828-0008 在网络用户界面中显示为“完成”。 有什么我想念的吗？
用于查询状态的端口与提交作业的端口是否正确？
更新： 在主日志上，我得到的只是
19/07/01 09:40:24 INFO master.Master: 172.31.15.245:42308 got disassociated, removing it.
