// AddJobFlowSteps adds new steps to a running cluster. A maximum of 256 steps are
// allowed in each job flow. If your cluster is long-running (such as a Hive data
// warehouse) or complex, you may require more than 256 steps to process your data.
// You can bypass the 256-step limitation in various ways, including using SSH to
// connect to the master node and submitting queries directly to the software
// running on the master node, such as Hive and Hadoop. A step specifies the
// location of a JAR file stored either on the master node of the cluster 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. Amazon EMR 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
// cluster that is in one of the following states: STARTING, BOOTSTRAPPING,
// RUNNING, or WAITING. The string values passed into HadoopJarStep object cannot
// exceed a total of 10240 characters.
