NAME

Paws::EMR::JobFlowDetail

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::EMR::JobFlowDetail object:

  $service_obj->Method(Att1 => { AmiVersion => $value, ..., VisibleToAllUsers => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::JobFlowDetail object:

  $result = $service_obj->Method(...);
  $result->Att1->AmiVersion

DESCRIPTION

A description of a cluster (job flow).

ATTRIBUTES

AmiVersion => Str

Applies only to Amazon EMR AMI versions 3.x and 2.x. For Amazon EMR releases 4.0 and later, "ReleaseLabel" is used. To specify a custom AMI, use "CustomAmiID".

An IAM role for automatic scaling policies. The default role is "EMR_AutoScaling_DefaultRole". The IAM role provides a way for the automatic scaling feature to get the required permissions it needs to launch and terminate EC2 instances in an instance group.

BootstrapActions => ArrayRef[Paws::EMR::BootstrapActionDetail]

A list of the bootstrap actions run by the job flow.

REQUIRED ExecutionStatusDetail => Paws::EMR::JobFlowExecutionStatusDetail

Describes the execution status of the job flow.

REQUIRED Instances => Paws::EMR::JobFlowInstancesDetail

Describes the Amazon EC2 instances of the job flow.

REQUIRED JobFlowId => Str

The job flow identifier.

JobFlowRole => Str

The IAM role that was specified when the job flow was launched. The EC2 instances of the job flow assume this role.

LogEncryptionKmsKeyId => Str

The AWS KMS customer master key (CMK) used for encrypting log files. This attribute is only available with EMR version 5.30.0 and later, excluding EMR 6.0.0.

LogUri => Str

The location in Amazon S3 where log files for the job are stored.

REQUIRED Name => Str

The name of the job flow.

ScaleDownBehavior => Str

The way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized. "TERMINATE_AT_INSTANCE_HOUR" indicates that Amazon EMR terminates nodes at the instance-hour boundary, regardless of when the request to terminate the instance was submitted. This option is only available with Amazon EMR 5.1.0 and later and is the default for clusters created using that version. "TERMINATE_AT_TASK_COMPLETION" indicates that Amazon EMR adds nodes to a deny list and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. "TERMINATE_AT_TASK_COMPLETION" available only in Amazon EMR version 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

ServiceRole => Str

The IAM role that is assumed by the Amazon EMR service to access AWS resources on your behalf.

Steps => ArrayRef[Paws::EMR::StepDetail]

A list of steps run by the job flow.

SupportedProducts => ArrayRef[Str|Undef]

A list of strings set by third-party software when the job flow is launched. If you are not using third-party software to manage the job flow, this value is empty.

VisibleToAllUsers => Bool

Indicates whether the cluster is visible to all IAM users of the AWS account associated with the cluster. 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 this value is "false", only the IAM user that created the cluster can perform actions. This value can be changed on a running cluster by using the SetVisibleToAllUsers action. You can override the default value of "true" when you create a cluster by using the "VisibleToAllUsers" parameter of the "RunJobFlow" action.
