@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 anAsyncHandler
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 interfaceAmazonElasticMapReduceAsync
- Parameters:
request
- The input argument to the AddJobFlowSteps operation.- Returns:

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 toTRUE
, 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 toTRUE
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.

setTerminationProtectionAsync
public Future<SetTerminationProtectionResult> 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 tofalse
.For more information, go to Protecting a Job Flow from Termination in the Amazon Elastic MapReduce Developer's Guide.

terminateJobFlowsAsync
public Future<TerminateJobFlowsResult> terminateJobFlowsAsync(TerminateJobFlowsRequest request)
Description copied from interface:AmazonElasticMapReduceAsync
TerminateJobFlows shuts a list of job flows down. When a job flow is shut down, any step not yet completed is canceled and the EC2 instances on which the job flow is running are stopped. Any log files not already saved are uploaded to Amazon S3 if a LogUri was specified when the job flow was created.
The maximum number of JobFlows allowed is 10. The call to TerminateJobFlows is asynchronous. Depending on the configuration of the job flow, it may take up to 5-20 minutes for the job flow to completely terminate and release allocated resources, such as Amazon EC2 instances.
