要检查 Apache Spark 中正在运行的应用程序，可以从 URL 上的 Web 界面检查它们:http://<master>:8080
我的问题是如何从终端检查正在运行的应用程序，是否有任何返回应用程序状态的命令？
请您参考如下方法:
如果是用于 Spark Standalone 或 Apache Mesos 集群管理器，@sb0709's answer是遵循的方式。
对于 YARN，您应该使用 yarn application命令:
$ yarn application -help
usage: application
-appStates <States> Works with -list to filter applications
based on input comma-separated list of
application states. The valid application
state can be one of the following:
ALL,NEW,NEW_SAVING,SUBMITTED,ACCEPTED,RUN
NING,FINISHED,FAILED,KILLED
-appTypes <Types> Works with -list to filter applications
based on input comma-separated list of
application types.
-help Displays help for all commands.
-kill <Application ID> Kills the application.
-list List applications. Supports optional use
of -appTypes to filter applications based
on application type, and -appStates to
filter applications based on application
state.
-movetoqueue <Application ID> Moves the application to a different
queue.
-queue <Queue Name> Works with the movetoqueue command to
specify which queue to move an
application to.
-status <Application ID> Prints the status of the application.
