Question

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？

Answer 1

如果是Spark Standalone或Apache Mesos集群管理器，则可以使用@sb0709's answer。

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.

Answer 2

您可以使用spark-submit --status（如Mastering Apache Spark 2.0中所述）。

spark-submit --status [submission ID]

请参阅code of spark-submit以获取参考：

if (!master.startsWith("spark://") && !master.startsWith("mesos://")) {
  SparkSubmit.printErrorAndExit(
    "Requesting submission statuses is only supported in standalone or Mesos mode!")
}

Answer 3

在我的情况下，我的spark应用程序远程运行在亚马逊的AWS EMR上。所以我使用Lynx命令行浏览器来访问spark应用程序的状态。当您从一个终端提交了火花作业时，打开另一个终端并从新终端发出以下命令。

   **lynx http://localhost:<4043 or other spark job port>**

我发现可以使用REST API提交，终止和获取Spark作业的状态。 REST API在端口6066上的master上公开。

要创建作业，请使用以下curl命令：

curl -X POST http://spark-cluster-ip:6066/v1/submissions/create 
   --header "Content-Type:application/json;charset=UTF-8"
   --data 
    '{
        "action" : "CreateSubmissionRequest",
        "appArgs" : [ "blah" ],
        "appResource" : "path-to-jar-file",
        "clientSparkVersion" : "2.2.0",
        "environmentVariables" : { "SPARK_ENV_LOADED" : "1" },
        "mainClass" : "app-class",
        "sparkProperties" : { 
            "spark.jars" : "path-to-jar-file",
            "spark.driver.supervise" : "false",
            "spark.app.name" : "app-name",
            "spark.submit.deployMode" : "cluster",
            "spark.master" : "spark://spark-master-ip:6066" 
         }
     }'

响应包括上述操作和submissionId

的成功或失败

{
   'submissionId': 'driver-20170829014216-0001',
   'serverSparkVersion': '2.2.0',
   'success': True,
   'message': 'Driver successfully submitted as driver-20170829014216-0001',
   'action': 'CreateSubmissionResponse'
}

要删除作业，请使用上面获得的submissionId：

 curl -X POST http://spark-cluster-ip:6066/v1/submissions/kill/driver-driver-20170829014216-0001

响应再次包含成功/失败状态：

{
     'success': True,
     'message': 'Kill request for driver-20170829014216-0001 submitted',
     'action': 'KillSubmissionResponse',
     'serverSparkVersion': '2.2.0',
     'submissionId': 'driver-20170829014216-0001'
}

要获取状态，请使用以下命令：

curl http://spark-cluster-ip:6066/v1/submissions/status/driver-20170829014216-0001

响应包括驱动程序状态 - 应用程序的当前状态：

{
  "action" : "SubmissionStatusResponse",
  "driverState" : "RUNNING",
  "serverSparkVersion" : "2.2.0",
  "submissionId" : "driver-20170829203736-0004",
  "success" : true,
  "workerHostPort" : "10.32.1.18:38317",
  "workerId" : "worker-20170829013941-10.32.1.18-38317"
}

我发现了REST API here。
