推荐答案

由于Spark在Hadoop Yarn上作为应用程序运行，因此您可以尝试

Since Spark runs as an application on Hadoop Yarn you can try

 sudo stop hadoop-yarn-resourcemanager  
 sudo start hadoop-yarn-resourcemanager  

如果您的意思是Spark History Server，则可以使用

If you meant the Spark History Server then you can use

 sudo stop spark-history-server  
 sudo start spark-history-server  

可以使用

sudo status hadoop-yarn-resourcemanager
sudo status spark-history-server

如 hadooper 所建议的那样，请使用EMR的最新版本

As hadooper suggested, for more recent versions of EMR use

sudo systemctl stop/start/status hadoop-yarn-resourcemanager
