Container for the parameters to the AddJobFlowSteps operation.

AddJobFlowSteps adds new steps to a running job flow. A maximum of 256 steps are allowed in each job flow.

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.

Elastic 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.

 
 public class AddJobFlowStepsRequest extends AmazonWebServiceRequest {

    
A string that uniquely identifies the job flow. This identifier is returned by RunJobFlow and can also be obtained from DescribeJobFlows .
