  • scope in which this resource is defined.
id System.String
  • scoped id of the resource.
props ICfnStepProps
  • resource properties.

CFN_RESOURCE_TYPE_NAME

The CloudFormation resource type name for this resource class.

public static string CFN_RESOURCE_TYPE_NAME { get; }
Property Value

System.String

CfnProperties

protected override IDictionary<string, object> CfnProperties { get; }
Property Value

System.Collections.Generic.IDictionary<System.String, System.Object>

Overrides

HadoopJarStep

The HadoopJarStepConfig property type specifies a job flow step consisting of a JAR file whose main function will be executed.

public virtual object HadoopJarStep { get; set; }
Property Value

System.Object

Remarks

The main function submits a job for the cluster to execute as a step on the master node, and then waits for the job to finish or fail before executing subsequent steps.
