使用 StartJobRun 提交作業執行

使用具有指定參數的 JSON 檔案來提交作業執行

  1. 建立 start-job-run-request.json 檔案並指定作業執行所需的參數，如下列範例 JSON 檔案所示。如需這些參數的詳細資訊，請參閱 用於設定作業執行的選項。

    {
  "name": "myjob", 
  "virtualClusterId": "123456",  
  "executionRoleArn": "iam_role_name_for_job_execution", 
  "releaseLabel": "emr-6.2.0-latest", 
  "jobDriver": {
    "sparkSubmitJobDriver": {
      "entryPoint": "entryPoint_location",
      "entryPointArguments": ["argument1", "argument2", ...],  
       "sparkSubmitParameters": "--class <main_class> --conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"
    }
  }, 
  "configurationOverrides": {
    "applicationConfiguration": [
      {
        "classification": "spark-defaults", 
        "properties": {
          "spark.driver.memory":"2G"
         }
      }
    ], 
    "monitoringConfiguration": {
      "persistentAppUI": "ENABLED", 
      "cloudWatchMonitoringConfiguration": {
        "logGroupName": "my_log_group", 
        "logStreamNamePrefix": "log_stream_prefix"
      }, 
      "s3MonitoringConfiguration": {
        "logUri": "s3://my_s3_log_location"
      }
    }
  }
}

  2. 搭配使用 start-job-run 命令與儲存在本機的 start-job-run-request.json 檔案路徑。

    aws emr-containers start-job-run \
--cli-input-json file://./start-job-run-request.json
使用 start-job-run 命令啟動作業執行

  1. 請在 StartJobRun 命令中提供所有指定的參數，如下列範例所示。

    aws emr-containers start-job-run \
--virtual-cluster-id 123456 \
--name myjob \
--execution-role-arn execution-role-arn \
--release-label emr-6.2.0-latest \
--job-driver '{"sparkSubmitJobDriver": {"entryPoint": "entryPoint_location", "entryPointArguments": ["argument1", "argument2", ...], "sparkSubmitParameters": "--class <main_class> --conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"}}' \
--configuration-overrides '{"applicationConfiguration": [{"classification": "spark-defaults", "properties": {"spark.driver.memory": "2G"}}], "monitoringConfiguration": {"cloudWatchMonitoringConfiguration": {"logGroupName": "log_group_name", "logStreamNamePrefix": "log_stream_prefix"}, "persistentAppUI":"ENABLED",  "s3MonitoringConfiguration": {"logUri": "s3://my_s3_log_location" }}}'

  2. 對於 Spark SQL，請在 StartJobRun 命令中提供所有指定的參數，如下列範例所示。

    aws emr-containers start-job-run \
--virtual-cluster-id 123456 \
--name myjob \
--execution-role-arn execution-role-arn \
--release-label emr-6.7.0-latest \
--job-driver '{"sparkSqlJobDriver": {"entryPoint": "entryPoint_location", "sparkSqlParameters": "--conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"}}' \
--configuration-overrides '{"applicationConfiguration": [{"classification": "spark-defaults", "properties": {"spark.driver.memory": "2G"}}], "monitoringConfiguration": {"cloudWatchMonitoringConfiguration": {"logGroupName": "log_group_name", "logStreamNamePrefix": "log_stream_prefix"}, "persistentAppUI":"ENABLED",  "s3MonitoringConfiguration": {"logUri": "s3://my_s3_log_location" }}}'
