@Deprecated void setEndpoint(String endpoint)
AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for
example:
builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
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.
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.@Deprecated void setRegion(Region region)
AwsClientBuilder#setRegion(String)setEndpoint(String), sets the regional endpoint for this
client's service calls. Callers can use this method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration supplied at construction.
This method is not threadsafe. A region 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.
region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.Region.getRegion(com.amazonaws.regions.Regions),
Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration),
Region.isServiceSupported(String)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.
addInstanceFleetRequest - 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.AddInstanceGroupsResult addInstanceGroups(AddInstanceGroupsRequest addInstanceGroupsRequest)
Adds one or more instance groups to a running cluster.
addInstanceGroupsRequest - Input to an AddInstanceGroups call.InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.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.

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 that a step will be canceled, even if the request is
successfully submitted. When you use Amazon EMR releases 5.28.0 and later, you can cancel steps that are in a
PENDING or RUNNING state. In earlier versions of Amazon EMR, you can only cancel steps
that are in a PENDING state.

Removes tags from an Amazon EMR resource, such as a cluster or Amazon EMR Studio. Tags make it easier to associate resources in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters.
The following example removes the stack tag with value Prod from a cluster:
removeTagsRequest - This input identifies an Amazon EMR resource and a list of tags to remove.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.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.
runJobFlowRequest - Input to the RunJobFlow operation.InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.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.
setKeepJobFlowAliveWhenNoStepsRequest - InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.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.
setTerminationProtectionRequest - The input argument to the TerminationProtection operation.InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.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.
setUnhealthyNodeReplacementRequest - InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.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.
setVisibleToAllUsersRequest - The input to the SetVisibleToAllUsers action.InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.StartNotebookExecutionResult startNotebookExecution(StartNotebookExecutionRequest startNotebookExecutionRequest)
Starts a notebook execution.
startNotebookExecutionRequest - 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.StopNotebookExecutionResult stopNotebookExecution(StopNotebookExecutionRequest stopNotebookExecutionRequest)
Stops a notebook execution.
stopNotebookExecutionRequest - InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.InvalidRequestException - This exception occurs when there is something wrong with user input.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.
terminateJobFlowsRequest - Input to the TerminateJobFlows operation.InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.UpdateStudioResult updateStudio(UpdateStudioRequest updateStudioRequest)
Updates an Amazon EMR Studio configuration, including attributes such as name, description, and subnets.
updateStudioRequest - 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.UpdateStudioSessionMappingResult updateStudioSessionMapping(UpdateStudioSessionMappingRequest updateStudioSessionMappingRequest)
Updates the session policy attached to the user or group for the specified Amazon EMR Studio.
updateStudioSessionMappingRequest - InternalServerErrorException - Indicates that an error occurred while processing the request and that the request was not completed.InvalidRequestException - This exception occurs when there is something wrong with user input.void shutdown()
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
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.
