Paws::EMR - Perl Interface to AWS Amazon Elastic MapReduce

  use Paws;
  my $obj = Paws->service('EMR');
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => 'Val1'  }, { Att1 => 'Val2' } ],
  );

Amazon EMR is a web service that makes it easier to process large amounts of data efficiently. Amazon EMR uses Hadoop processing combined with several AWS services to do tasks such as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehouse management.

For the AWS API documentation, see <https://docs.aws.amazon.com/goto/WebAPI/elasticmapreduce-2009-03-31>

Each argument is described in detail in: Paws::EMR::AddInstanceFleet

Returns: a Paws::EMR::AddInstanceFleetOutput instance

Adds an instance fleet to a running cluster.

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

Each argument is described in detail in: Paws::EMR::AddInstanceGroups

Returns: a Paws::EMR::AddInstanceGroupsOutput instance

Adds one or more instance groups to a running cluster.

Each argument is described in detail in: Paws::EMR::AddJobFlowSteps

Returns: a Paws::EMR::AddJobFlowStepsOutput instance

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 (https://docs.aws.amazon.com/emr/latest/ManagementGuide/AddMoreThan256Steps.html) 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.

Each argument is described in detail in: Paws::EMR::AddTags

Returns: a Paws::EMR::AddTagsOutput instance

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 (https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-plan-tags.html).

[StepCancellationOption => Str]

Each argument is described in detail in: Paws::EMR::CancelSteps

Returns: a Paws::EMR::CancelStepsOutput instance

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. You can only cancel steps that are in a "PENDING" state.

[Tags => ArrayRef[Paws::EMR::Tag]]
[VisibleToAllUsers => Bool]

Each argument is described in detail in: Paws::EMR::RunJobFlow

Returns: a Paws::EMR::RunJobFlowOutput instance

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 (https://docs.aws.amazon.com/emr/latest/ManagementGuide/AddMoreThan256Steps.html) 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.

Each argument is described in detail in: Paws::EMR::SetTerminationProtection

Returns: nothing

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 (https://docs.aws.amazon.com/emr/latest/ManagementGuide/UsingEMR_TerminationProtection.html) in the Amazon EMR Management Guide.

Each argument is described in detail in: Paws::EMR::SetVisibleToAllUsers

Returns: nothing

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".

[NotebookExecutionName => Str]
[NotebookInstanceSecurityGroupId => Str]
[NotebookParams => Str]
[Tags => ArrayRef[Paws::EMR::Tag]]

Each argument is described in detail in: Paws::EMR::StartNotebookExecution

Returns: a Paws::EMR::StartNotebookExecutionOutput instance

Starts a notebook execution.

Each argument is described in detail in: Paws::EMR::StopNotebookExecution

Returns: nothing

Stops a notebook execution.

Each argument is described in detail in: Paws::EMR::TerminateJobFlows

Returns: nothing

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.

[DefaultS3Location => Str]
[Description => Str]
[Name => Str]
[SubnetIds => ArrayRef[Str|Undef]]

Each argument is described in detail in: Paws::EMR::UpdateStudio

[IdentityId => Str]
[IdentityName => Str]
