com.amazonaws.services.elasticmapreduce

Interface AmazonElasticMapReduce

    • Method Detail

      • setEndpoint

        @Deprecated
void setEndpoint(String endpoint)
        Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
        Overrides the default endpoint for this client ("https://elasticmapreduce.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

        Callers can pass in just the endpoint (ex: "elasticmapreduce.amazonaws.com") or a full URL, including the protocol (ex: "https://elasticmapreduce.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

        For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint

        This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

        Parameters:
        endpoint - The endpoint (ex: "elasticmapreduce.amazonaws.com") or a full URL, including the protocol (ex: "https://elasticmapreduce.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

      • addInstanceFleet

        AddInstanceFleetResult addInstanceFleet(AddInstanceFleetRequest addInstanceFleetRequest)

        Adds an instance fleet to a running cluster.

        The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x.

        Parameters:
        addInstanceFleetRequest -
        Returns:
        Result of the AddInstanceFleet operation returned by the service.
        Throws:
        InternalServerException - This exception occurs when there is an internal failure in the Amazon EMR service.
        InvalidRequestException - This exception occurs when there is something wrong with user input.

      • addJobFlowSteps

        AddJobFlowStepsResult addJobFlowSteps(AddJobFlowStepsRequest addJobFlowStepsRequest)

        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.

        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.

      • runJobFlow

        RunJobFlowResult runJobFlow(RunJobFlowRequest runJobFlowRequest)

        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 long-running clusters, we recommend that you periodically store your results.

        The instance fleets configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions. The RunJobFlow request can contain InstanceFleets parameters or InstanceGroups parameters, but not both.

        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.

      • setKeepJobFlowAliveWhenNoSteps

        SetKeepJobFlowAliveWhenNoStepsResult setKeepJobFlowAliveWhenNoSteps(SetKeepJobFlowAliveWhenNoStepsRequest setKeepJobFlowAliveWhenNoStepsRequest)

        You can use the SetKeepJobFlowAliveWhenNoSteps to configure a cluster (job flow) to terminate after the step execution, i.e., all your steps are executed. If you want a transient cluster that shuts down after the last of the current executing steps are completed, you can configure SetKeepJobFlowAliveWhenNoSteps to false. If you want a long running cluster, configure SetKeepJobFlowAliveWhenNoSteps to true.

        For more information, see Managing Cluster Termination in the Amazon EMR Management Guide.

        Parameters:
        setKeepJobFlowAliveWhenNoStepsRequest -
        Returns:
        Result of the SetKeepJobFlowAliveWhenNoSteps operation returned by the service.
        Throws:
        InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.

      • setTerminationProtection

        SetTerminationProtectionResult setTerminationProtection(SetTerminationProtectionRequest setTerminationProtectionRequest)

        SetTerminationProtection locks a cluster (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 cluster is similar to calling the Amazon EC2 DisableAPITermination API on all Amazon 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, see Managing Cluster Termination in the Amazon EMR Management Guide.

        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.

      • setUnhealthyNodeReplacement

        SetUnhealthyNodeReplacementResult setUnhealthyNodeReplacement(SetUnhealthyNodeReplacementRequest setUnhealthyNodeReplacementRequest)

        Specify whether to enable unhealthy node replacement, which lets Amazon EMR gracefully replace core nodes on a cluster if any nodes become unhealthy. For example, a node becomes unhealthy if disk usage is above 90%. If unhealthy node replacement is on and TerminationProtected are off, Amazon EMR immediately terminates the unhealthy core nodes. To use unhealthy node replacement and retain unhealthy core nodes, use to turn on termination protection. In such cases, Amazon EMR adds the unhealthy nodes to a denylist, reducing job interruptions and failures.

        If unhealthy node replacement is on, Amazon EMR notifies YARN and other applications on the cluster to stop scheduling tasks with these nodes, moves the data, and then terminates the nodes.

        For more information, see graceful node replacement in the Amazon EMR Management Guide.

        Parameters:
        setUnhealthyNodeReplacementRequest -
        Returns:
        Result of the SetUnhealthyNodeReplacement operation returned by the service.
        Throws:
        InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.

      • setVisibleToAllUsers

        SetVisibleToAllUsersResult setVisibleToAllUsers(SetVisibleToAllUsersRequest setVisibleToAllUsersRequest)

        The SetVisibleToAllUsers parameter is no longer supported. Your cluster may be visible to all users in your account. To restrict cluster access using an IAM policy, see Identity and Access Management for Amazon EMR.

        Sets the Cluster$VisibleToAllUsers value for an Amazon EMR cluster. When true, IAM principals in the Amazon Web Services account can perform Amazon EMR cluster actions that their IAM policies allow. When false, only the IAM principal that created the cluster and the Amazon Web Services account root user can perform Amazon EMR actions on the cluster, regardless of IAM permissions policies attached to other IAM principals.

        This action works on running clusters. When you create a cluster, use the RunJobFlowInput$VisibleToAllUsers parameter.

        For more information, see Understanding the Amazon EMR Cluster VisibleToAllUsers Setting in the Amazon EMR Management Guide.

        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

        TerminateJobFlowsResult terminateJobFlows(TerminateJobFlowsRequest terminateJobFlowsRequest)

        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 Amazon 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.

        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.

      • updateStudio

        UpdateStudioResult updateStudio(UpdateStudioRequest updateStudioRequest)

        Updates an Amazon EMR Studio configuration, including attributes such as name, description, and subnets.

        Parameters:
        updateStudioRequest -
        Returns:
        Result of the UpdateStudio operation returned by the service.
        Throws:
        InternalServerException - This exception occurs when there is an internal failure in the Amazon EMR service.
        InvalidRequestException - This exception occurs when there is something wrong with user input.

      • shutdown

        void shutdown()
        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.

      • getCachedResponseMetadata

        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 a request.

        Parameters:
        request - The originally executed request.
        Returns:
        The response metadata for the specified request, or null if none is available.
