=head1 NAME

Paws::EMR::AddInstanceGroups - Arguments for method AddInstanceGroups on L<Paws::EMR>

=head1 DESCRIPTION

This class represents the parameters used for calling the method AddInstanceGroups on the
L<Amazon Elastic MapReduce|Paws::EMR> 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.

    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.
