    AWS API Documentation
  - addJobFlowSteps
```
public AddJobFlowStepsResult addJobFlowSteps(AddJobFlowStepsRequest request)
```
    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. For more information on how to do this, see Add More than 256 Steps to a Cluster in the Amazon EMR Management Guide.
    
    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.
    
    Specified by:
    
    addJobFlowSteps in interface AmazonElasticMapReduce
    
    Parameters:
    
    addJobFlowStepsRequest - The input argument to the AddJobFlowSteps operation.
    
    Returns:
    
    Result of the AddJobFlowSteps operation returned by the service.
    
    Throws:
    
    InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.
    
    See Also:
    
    AWS API Documentation
  - addTags
```
public AddTagsResult addTags(AddTagsRequest request)
```
    Adds tags to an Amazon EMR resource. Tags make it easier to associate clusters in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters.
    
    Specified by:
    
    addTags in interface AmazonElasticMapReduce
    
    Parameters:
    
    addTagsRequest - This input identifies a cluster and a list of tags to attach.
    
    Returns:
    
    Result of the AddTags operation returned by the service.
    
    Throws:
    
    InternalServerException - This exception occurs when there is an internal failure in the EMR service.
    
    InvalidRequestException - This exception occurs when there is something wrong with user input.

  - cancelSteps
```
public CancelStepsResult cancelSteps(CancelStepsRequest request)
```
    Cancels a pending step or steps in a running cluster. Available only in Amazon EMR versions 4.8.0 and later, excluding version 5.0.0. A maximum of 256 steps are allowed in each CancelSteps request. CancelSteps is idempotent but asynchronous; it does not guarantee a step will be canceled, even if the request is successfully submitted. You can only cancel steps that are in a PENDING state.
    
    Specified by:
    
    cancelSteps in interface AmazonElasticMapReduce
    
    Parameters:
    
    cancelStepsRequest - The input argument to the CancelSteps operation.

  - runJobFlow
```
public RunJobFlowResult runJobFlow(RunJobFlowRequest request)
```
    RunJobFlow creates and starts running a new cluster (job flow). The cluster runs the steps specified. After the steps complete, the cluster stops 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 cluster transitions 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 cluster 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 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 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 Cluster in the Amazon EMR Management Guide.
    
    For long running clusters, we recommend that you periodically store your results.
    
    The instance fleets configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions. The RunJobFlow request can contain InstanceFleets parameters or InstanceGroups parameters, but not both.
    
    Specified by:
    
    runJobFlow in interface AmazonElasticMapReduce
    
    Parameters:
    
    runJobFlowRequest - Input to the RunJobFlow operation.
    
    Returns:
    
    Result of the RunJobFlow operation returned by the service.
    
    Throws:
    
    InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.
    
    See Also:
    
    AWS API Documentation
  - setTerminationProtection
```
public SetTerminationProtectionResult setTerminationProtection(SetTerminationProtectionRequest request)
```
    SetTerminationProtection locks a cluster (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. The cluster still terminates upon successful completion of the job flow. Calling SetTerminationProtection on a cluster is similar to calling the Amazon EC2 DisableAPITermination API on all EC2 instances in a cluster.
    
    SetTerminationProtection is used to prevent accidental termination of a cluster and to ensure that in the event of an error, the instances persist so that you can recover any data stored in their ephemeral instance storage.
    
    To terminate a cluster 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, seeManaging Cluster Termination in the Amazon EMR Management Guide.
    
    Specified by:
    
    setTerminationProtection in interface AmazonElasticMapReduce
    
    Parameters:
    
    setTerminationProtectionRequest - The input argument to the TerminationProtection operation.
    
    Returns:
    
    Result of the SetTerminationProtection operation returned by the service.
    
    Throws:
    
    InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.
    
    See Also:
    
    AWS API Documentation
  - setVisibleToAllUsers
```
public SetVisibleToAllUsersResult setVisibleToAllUsers(SetVisibleToAllUsersRequest request)
```
    Sets the Cluster$VisibleToAllUsers value, which determines whether the cluster is visible to all IAM users of the AWS account associated with the cluster. Only the IAM user who created the cluster or the AWS account root user can call this action. The default value, true, indicates that all IAM users in the AWS account can perform cluster actions if they have the proper IAM policy permissions. If set to false, only the IAM user that created the cluster can perform actions. This action works on running clusters. You can override the default true setting when you create a cluster by using the VisibleToAllUsers parameter with RunJobFlow.
    
    Specified by:
    
    setVisibleToAllUsers in interface AmazonElasticMapReduce
    
    Parameters:
    
    setVisibleToAllUsersRequest - The input to the SetVisibleToAllUsers action.
    
    Returns:
    
    Result of the SetVisibleToAllUsers operation returned by the service.
    
    Throws:
    
    InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.

  - terminateJobFlows
```
public TerminateJobFlowsResult terminateJobFlows(TerminateJobFlowsRequest request)
```
    TerminateJobFlows shuts a list of clusters (job flows) down. When a job flow is shut down, any step not yet completed is canceled and the EC2 instances on which the cluster is running are stopped. Any log files not already saved are uploaded to Amazon S3 if a LogUri was specified when the cluster was created.
    
    The maximum number of clusters allowed is 10. The call to TerminateJobFlows is asynchronous. Depending on the configuration of the cluster, it may take up to 1-5 minutes for the cluster to completely terminate and release allocated resources, such as Amazon EC2 instances.
    
    Specified by:
    
    terminateJobFlows in interface AmazonElasticMapReduce
    
    Parameters:
    
    terminateJobFlowsRequest - Input to the TerminateJobFlows operation.
    
    Returns:
    
    Result of the TerminateJobFlows operation returned by the service.
    
    Throws:
    
    InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.

  - getCachedResponseMetadata
```
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AmazonElasticMapReduce
    
    Parameters:
    
    request - The originally executed request
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.

    Description copied from interface: AmazonElasticMapReduce
    
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
