Amazon EMR Construct Library

This module is part of the AWS Cloud Development Kit project.

import emr "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::EMR.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

A CloudFormation `AWS::EMR::Cluster`.

The `AWS::EMR::Cluster` resource specifies an Amazon EMR cluster. This cluster is a collection of Amazon EC2 instances that run open source big data frameworks and applications to process and analyze vast amounts of data. For more information, see the [Amazon EMR Management Guide](https://docs.aws.amazon.com//emr/latest/ManagementGuide/) .

Amazon EMR now supports launching task instance groups and task instance fleets as part of the `AWS::EMR::Cluster` resource. This can be done by using the `JobFlowInstancesConfig` property type's `TaskInstanceGroups` and `TaskInstanceFleets` subproperties. Using these subproperties reduces delays in provisioning task nodes compared to specifying task nodes with the `AWS::EMR::InstanceGroupConfig` and `AWS::EMR::InstanceFleetConfig` resources. Please refer to the examples at the bottom of this page to learn how to use these subproperties.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

	Name *string `field:"optional" json:"name" yaml:"name"`
	// The version of the application.
	Version *string `field:"optional" json:"version" yaml:"version"`
}

`Application` is a property of `AWS::EMR::Cluster` .

The `Application` property type defines the open-source big data applications for EMR to install and configure when a cluster is created.

With Amazon EMR release version 4.0 and later, the only accepted parameter is the application `Name` . To pass arguments to these applications, you use configuration classifications specified using JSON objects in a `Configuration` property. For more information, see [Configuring Applications](https://docs.aws.amazon.com//emr/latest/ReleaseGuide/emr-configure-apps.html) .

With earlier Amazon EMR releases, the application is any AWS or third-party software that you can add to the cluster. You can specify the version of the application and arguments to pass to it. Amazon EMR accepts and forwards the argument list to the corresponding installation script as a bootstrap action argument.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

The main function submits a job for the cluster to execute as a step on the master node, and then waits for the job to finish or fail before executing subsequent steps.

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

`JobFlowInstancesConfig` is a property of the `AWS::EMR::Cluster` resource.

`JobFlowInstancesConfig` defines the instance groups or instance fleets that comprise the cluster. `JobFlowInstancesConfig` must contain either `InstanceFleetConfig` or `InstanceGroupConfig` . They cannot be used together.

You can now define task instance groups or task instance fleets using the `TaskInstanceGroups` and `TaskInstanceFleets` subproperties. Using these subproperties reduces delays in provisioning task nodes compared to specifying task nodes with the `InstanceFleetConfig` and `InstanceGroupConfig` resources.

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

stepConfigProperty := &stepConfigProperty{
	hadoopJarStep: &hadoopJarStepConfigProperty{

}

type CfnCluster_VolumeSpecificationProperty 

type CfnCluster_VolumeSpecificationProperty struct {
	// The volume size, in gibibytes (GiB).
	//
	// This can be a number from 1 - 1024. If the volume type is EBS-optimized, the minimum value is 10.
	SizeInGb *float64 `field:"required" json:"sizeInGb" yaml:"sizeInGb"`

	// The number of I/O operations per second (IOPS) that the volume supports.
	Iops *float64 `field:"optional" json:"iops" yaml:"iops"`
}

`VolumeSpecification` is a subproperty of the `EbsBlockDeviceConfig` property type.

`VolumeSecification` determines the volume type, IOPS, and size (GiB) for EBS volumes attached to EC2 instances.

A CloudFormation `AWS::EMR::InstanceFleetConfig`.

Use `InstanceFleetConfig` to define instance fleets for an EMR cluster. A cluster can not use both instance fleets and instance groups. For more information, see [Configure Instance Fleets](https://docs.aws.amazon.com//emr/latest/ManagementGuide/emr-instance-group-configuration.html) in the *Amazon EMR Management Guide* .

> The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions. > You can currently only add a task instance fleet to a cluster with this resource. If you use this resource, CloudFormation waits for the cluster launch to complete before adding the task instance fleet to the cluster. In order to add a task instance fleet to the cluster as part of the cluster launch and minimize delays in provisioning task nodes, use the `TaskInstanceFleets` subproperty for the [AWS::EMR::Cluster JobFlowInstancesConfig](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticmapreduce-cluster-jobflowinstancesconfig.html) property instead. To use this subproperty, see [AWS::EMR::Cluster](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticmapreduce-cluster.html) for examples.

A CloudFormation `AWS::EMR::InstanceGroupConfig`.

Use `InstanceGroupConfig` to define instance groups for an EMR cluster. A cluster can not use both instance groups and instance fleets. For more information, see [Create a Cluster with Instance Fleets or Uniform Instance Groups](https://docs.aws.amazon.com//emr/latest/ManagementGuide/emr-instance-group-configuration.html) in the *Amazon EMR Management Guide* .

> You can currently only add task instance groups to a cluster with this resource. If you use this resource, CloudFormation waits for the cluster launch to complete before adding the task instance group to the cluster. In order to add task instance groups to the cluster as part of the cluster launch and minimize delays in provisioning task nodes, use the `TaskInstanceGroups` subproperty for the [AWS::EMR::Cluster JobFlowInstancesConfig](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticmapreduce-cluster-jobflowinstancesconfig.html) property instead. To use this subproperty, see [AWS::EMR::Cluster](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticmapreduce-cluster.html) for examples.

`Configurations` is a property of the `AWS::EMR::Cluster` resource that specifies the configuration of applications on an Amazon EMR cluster.

Configurations are optional. You can use them to have EMR customize applications and software bundled with Amazon EMR when a cluster is created. A configuration consists of a classification, properties, and optional nested configurations. A classification refers to an application-specific configuration file. Properties are the settings you want to change in that file. For more information, see [Configuring Applications](https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-configure-apps.html) .
