NAME

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

DESCRIPTION

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

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

# Results:
my $ClusterArn       = $AddInstanceGroupsOutput->ClusterArn;
my $InstanceGroupIds = $AddInstanceGroupsOutput->InstanceGroupIds;
my $JobFlowId        = $AddInstanceGroupsOutput->JobFlowId;

# Returns a L<Paws::EMR::AddInstanceGroupsOutput> 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/AddInstanceGroups

ATTRIBUTES

REQUIRED InstanceGroups => ArrayRef[Paws::EMR::InstanceGroupConfig]

Instance groups to add.

REQUIRED JobFlowId => Str

Job flow in which to add the instance groups.
