First time using the AWS CLI? See the User Guide for help getting started.

Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

get-managed-scaling-policy

Description

Fetches the attached managed scaling policy for an Amazon EMR cluster.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-managed-scaling-policy
--cluster-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--cluster-id (string)

Specifies the ID of the cluster for which the managed scaling policy will be fetched.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

ManagedScalingPolicy -> (structure)

Specifies the managed scaling policy that is attached to an Amazon EMR cluster.

ComputeLimits -> (structure)

The EC2 unit limits for a managed scaling policy. The managed scaling activity of a cluster is not allowed to go above or below these limits. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

UnitType -> (string)

The unit type used for specifying a managed scaling policy.

MinimumCapacityUnits -> (integer)

The lower boundary of EC2 units. It is measured through VCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

MaximumCapacityUnits -> (integer)

The upper boundary of EC2 units. It is measured through VCPU cores or instances for instance groups and measured through units for instance fleets. Managed scaling activities are not allowed beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

MaximumOnDemandCapacityUnits -> (integer)

The upper boundary of on-demand EC2 units. It is measured through VCPU cores or instances for instance groups and measured through units for instance fleets. The on-demand units are not allowed to scale beyond this boundary. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.
