AmazonElasticMapReduceAsyncAddJobFlowSteps adds new steps to a running job flow. A maximum of 256 steps are allowed in each job flow.
If your job flow 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 the SSH shell to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop. For more information on how to do this, see Add More than 256 Steps to a Job Flow in the Amazon EMR Developer's Guide.
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.
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 job flow that is in one of the following states: STARTING, BOOTSTRAPPING, RUNNING, or WAITING.

AmazonElasticMapReduceAsync
RunJobFlow creates and starts running a new job flow. The job flow will run the steps specified. After the job
flow completes, the cluster is stopped and the HDFS partition is lost. To prevent loss of data, configure the
last step of the job flow to store results in Amazon S3. If the JobFlowInstancesConfig
KeepJobFlowAliveWhenNoSteps parameter is set to TRUE, the job flow will transition to
the WAITING state rather than shutting down after the steps have completed.
For additional protection, you can set the JobFlowInstancesConfig TerminationProtected
parameter to TRUE to lock the job flow and prevent it from being terminated by API call, user
intervention, or in the event of a job flow error.
A maximum of 256 steps are allowed in each job flow.
If your job flow 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 the SSH shell to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop. For more information on how to do this, see Add More than 256 Steps to a Job Flow in the Amazon EMR Management Guide.
For long running job flows, we recommend that you periodically store your results.

AmazonElasticMapReduceAsyncSetTerminationProtection locks a job flow so the EC2 instances in the cluster cannot be terminated by user intervention, an API call, or in the event of a job-flow error.

Calling SetTerminationProtection on a job flow is analogous to calling the Amazon EC2 DisableAPITermination API on all of the EC2 instances in a cluster.
SetTerminationProtection is used to prevent accidental termination of a job flow and to ensure that in the event of an error, the instances will persist so you can recover any data stored in their ephemeral instance storage.
To terminate a job flow that has been locked by setting SetTerminationProtection to true, you must
first unlock the job flow by a subsequent call to SetTerminationProtection in which you set the value to
false.
