Class AddJobFlowStepsRequest

  com.amazonaws.AmazonWebServiceRequest
      com.amazonaws.services.elasticmapreduce.model.AddJobFlowStepsRequest

public class AddJobFlowStepsRequest
extends AmazonWebServiceRequest

Container for the parameters to the AddJobFlowSteps operation.

AddJobFlowSteps adds new steps to a running job flow. The maximum number of steps in a job flow is 256.

A step specifies the location of a JAR file stored either on the master node of the job flow or in Amazon S3. Each step is performed by the main function of the main class of the JAR file. The main class can be specified either in the manifest of the JAR or by using the MainFunction parameter of the step.

SElastic MapReduce executes each step in the order listed. For a step to be considered complete, the main function must exit with a zero exit code and all Hadoop jobs started while the step was running must have completed and run successfully.

You can only add steps to a job flow that is in one of the following states: STARTING, BOOTSTAPPING, RUNNING or WAITING.
