@ThreadSafe
public class AmazonElasticMapReduceAsyncClient
extends AmazonElasticMapReduceClient
implements AmazonElasticMapReduceAsync
```
Interface for accessing Amazon EMR asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an AsyncHandler can be used to receive notification when an asynchronous operation completes.

Amazon Elastic MapReduce (Amazon EMR) is a web service that makes it easy to process large amounts of data efficiently. Amazon EMR uses Hadoop processing combined with several AWS products to do tasks such as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehousing.

  - addJobFlowStepsAsync
```
public Future<AddJobFlowStepsResult> addJobFlowStepsAsync(AddJobFlowStepsRequest request)
```
    Description copied from interface: AmazonElasticMapReduceAsync
    
    AddJobFlowSteps 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, go to Add More than 256 Steps to a Job Flow in the Amazon Elastic MapReduce 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.
    
    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, BOOTSTRAPPING, RUNNING, or WAITING.
    
    Specified by:
    
    addJobFlowStepsAsync in interface AmazonElasticMapReduceAsync
    
    Parameters:
    request - The input argument to the AddJobFlowSteps operation.
    
    Returns:
    A Java Future containing the result of the AddJobFlowSteps operation returned by the service.

  - runJobFlowAsync
```
public Future<RunJobFlowResult> runJobFlowAsync(RunJobFlowRequest request)
```
    Description copied from interface: AmazonElasticMapReduceAsync
    
    RunJobFlow creates and starts running a new job flow. The job flow will run the steps specified. Once 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 once 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, go to Add More than 256 Steps to a Job Flow in the Amazon Elastic MapReduce Developer's Guide.
    
    For long running job flows, we recommend that you periodically store your results.
    
    Specified by:
    
    runJobFlowAsync in interface AmazonElasticMapReduceAsync
    
    Parameters:

  - setTerminationProtectionAsync
```
public Future<Void> setTerminationProtectionAsync(SetTerminationProtectionRequest request)
```
    Description copied from interface: AmazonElasticMapReduceAsync
    
    SetTerminationProtection locks a job flow so the Amazon EC2 instances in the cluster cannot be terminated by user intervention, an API call, or in the event of a job-flow error. The cluster still terminates upon successful completion of the job flow. 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.
    
    For more information, go to Protecting a Job Flow from Termination in the Amazon Elastic MapReduce Developer's Guide.
    
    Specified by:
    
    setTerminationProtectionAsync in interface AmazonElasticMapReduceAsync
