Interface CfnCluster.IHadoopJarStepConfigProperty

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

Namespace: Amazon.CDK.AWS.EMR

Assembly: Amazon.CDK.AWS.EMR.dll

Syntax (csharp)

public interface IHadoopJarStepConfigProperty

Syntax (vb)

Public Interface IHadoopJarStepConfigProperty

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.
