NAME

Paws::EMR::ListInstances - Arguments for method ListInstances on Paws::EMR

DESCRIPTION

This class represents the parameters used for calling the method ListInstances on the Amazon Elastic MapReduce service. Use the attributes of this class as arguments to method ListInstances.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to ListInstances.

SYNOPSIS

    my $elasticmapreduce = Paws->service('EMR');
    my $ListInstancesOutput = $elasticmapreduce->ListInstances(
      ClusterId          => 'MyClusterId',
      InstanceFleetId    => 'MyInstanceFleetId',    # OPTIONAL
      InstanceFleetType  => 'MASTER',               # OPTIONAL
      InstanceGroupId    => 'MyInstanceGroupId',    # OPTIONAL
      InstanceGroupTypes => [
        'MASTER', ...                               # values: MASTER, CORE, TASK
      ],    # OPTIONAL
      InstanceStates => [
        'AWAITING_FULFILLMENT',
        ... # values: AWAITING_FULFILLMENT, PROVISIONING, BOOTSTRAPPING, RUNNING, TERMINATED
      ],    # OPTIONAL
      Marker => 'MyMarker',    # OPTIONAL
    );

    # Results:
    my $Instances = $ListInstancesOutput->Instances;
    my $Marker    = $ListInstancesOutput->Marker;

    # Returns a L<Paws::EMR::ListInstancesOutput> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/elasticmapreduce/ListInstances

ATTRIBUTES

REQUIRED ClusterId => Str

The identifier of the cluster for which to list the instances.

InstanceFleetId => Str

The unique identifier of the instance fleet.

InstanceFleetType => Str

The node type of the instance fleet. For example MASTER, CORE, or TASK.

Valid values are: "MASTER", "CORE", "TASK"

InstanceGroupId => Str

The identifier of the instance group for which to list the instances.

InstanceGroupTypes => ArrayRef[Str|Undef]

The type of instance group for which to list the instances.

InstanceStates => ArrayRef[Str|Undef]

A list of instance states that will filter the instances returned with this request.

Marker => Str

The pagination token that indicates the next set of results to retrieve.
