Apache spark 更改配置设置后，如何在EMR中重新启动Spark服务？

我正在使用EMR-5.9.0，在更改一些配置文件后，我想重新启动服务以查看效果。我怎样才能做到这一点

我尝试使用initctl list查找服务的名称，正如我在其他答案中看到的那样，但没有成功…

因为Spark作为Hadoop上的应用程序运行，所以您可以尝试

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

如果您指的是Spark历史服务器，那么您可以使用

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

检查服务的状态可以使用

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

编辑：
正如所建议的，对于EMR的最新版本，请使用

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

在5.x EMR集群中，您还可以执行以下操作：

[hadoop@ip-10-0-2-93 conf]$ initctl list | grep yarn
hadoop-yarn-timelineserver start/running, process 10632
hadoop-yarn-resourcemanager start/running, process 10771
hadoop-yarn-proxyserver start/running, process 10508

[hadoop@ip-10-0-2-93 conf]$ sudo stop hadoop-yarn-resourcemanager
hadoop-yarn-resourcemanager stop/waiting

[hadoop@ip-10-0-2-93 conf]$ sudo start hadoop-yarn-resourcemanager
hadoop-yarn-resourcemanager start/running, process 1591

[hadoop@ip-10-0-2-93 conf]$ initctl list | grep yarn
hadoop-yarn-timelineserver start/running, process 10632
hadoop-yarn-resourcemanager start/running, process 1591
hadoop-yarn-proxyserver start/running, process 10508

你找到了吗？当我尝试启动spark history server时，我遇到了与Hive相同的问题：我遇到了以下错误开始：作业无法启动任何想法？对于尝试最新EMR版本的用户，请将命令更改为

sudo systemctl stop hadoop warn resourcemanager
