=head1 NAME

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

=head1 DESCRIPTION

This class represents the parameters used for calling the method RunJobFlow on the
L<Amazon Elastic MapReduce|Paws::EMR> service. Use the attributes of this class
as arguments to method RunJobFlow.

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

=head2 CustomAmiId => Str

Available only in Amazon EMR version 5.7.0 and later. The ID of a

custom AMIs in Amazon EMR, see Using a Custom AMI
(https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-custom-ami.html)
in the I<Amazon EMR Management Guide>. If omitted, the cluster uses the
base Linux AMI for the C<ReleaseLabel> specified. For Amazon EMR
versions 2.x and 3.x, use C<AmiVersion> instead.

For information about creating a custom AMI, see Creating an Amazon
EBS-Backed Linux AMI
(https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-an-ami-ebs.html)
in the I<Amazon Elastic Compute Cloud User Guide for Linux Instances>.

A specification of the number and type of Amazon EC2 instances.


=head2 JobFlowRole => Str

Also called instance profile and EC2 role. An IAM role for an EMR
cluster. The EC2 instances of the cluster assume this role. The default
role is C<EMR_EC2_DefaultRole>. In order to use the default role, you
must have already created it using the CLI or console.


=head2 KerberosAttributes => L<Paws::EMR::KerberosAttributes>

Attributes for Kerberos configuration when Kerberos authentication is
enabled using a security configuration. For more information see Use
Kerberos Authentication

in the I<Amazon EMR Management Guide>.


=head2 LogEncryptionKmsKeyId => Str

The AWS KMS customer master key (CMK) used for encrypting log files. If
a value is not provided, the logs remain encrypted by AES-256. This
attribute is only available with Amazon EMR version 5.30.0 and later,
excluding Amazon EMR 6.0.0.


=head2 LogUri => Str

The location in Amazon S3 to write the log files of the job flow. If a
value is not provided, logs are not created.


=head2 ManagedScalingPolicy => L<Paws::EMR::ManagedScalingPolicy>

The specified managed scaling policy for an Amazon EMR cluster.


=head2 B<REQUIRED> Name => Str

The name of the job flow.


=head2 NewSupportedProducts => ArrayRef[L<Paws::EMR::SupportedProductConfig>]

For Amazon EMR releases 3.x and 2.x. For Amazon EMR releases 4.x and
later, use Applications.

A list of strings that indicates third-party software to use with the
job flow that accepts a user argument list. EMR accepts and forwards
the argument list to the corresponding installation script as bootstrap
action arguments. For more information, see "Launch a Job Flow on the
MapR Distribution for Hadoop" in the Amazon EMR Developer Guide
(https://docs.aws.amazon.com/emr/latest/DeveloperGuide/emr-dg.pdf).
Supported values are:

=over

=item *

"mapr-m3" - launch the cluster using MapR M3 Edition.

=item *

"mapr-m5" - launch the cluster using MapR M5 Edition.

=item *

"mapr" with the user arguments specifying "--edition,m3" or
"--edition,m5" - launch the job flow using MapR M3 or M5 Edition
respectively.

=item *

"mapr-m7" - launch the cluster using MapR M7 Edition.

=item *

"hunk" - launch the cluster with the Hunk Big Data Analytics Platform.

=item *

"hue"- launch the cluster with Hue installed.

=item *

"spark" - launch the cluster with Apache Spark installed.

=item *

"ganglia" - launch the cluster with the Ganglia Monitoring System
installed.

=back


=head2 PlacementGroupConfigs => ArrayRef[L<Paws::EMR::PlacementGroupConfig>]

The specified placement group configuration for an Amazon EMR cluster.


=head2 ReleaseLabel => Str

The Amazon EMR release label, which determines the version of
open-source application packages installed on the cluster. Release
labels are in the form C<emr-x.x.x>, where x.x.x is an Amazon EMR
release version such as C<emr-5.14.0>. For more information about
Amazon EMR release versions and included application versions and
features, see https://docs.aws.amazon.com/emr/latest/ReleaseGuide/
(https://docs.aws.amazon.com/emr/latest/ReleaseGuide/). The release
label applies only to Amazon EMR releases version 4.0 and later.
Earlier versions use C<AmiVersion>.


=head2 RepoUpgradeOnBoot => Str

Applies only when C<CustomAmiID> is used. Specifies which updates from
the Amazon Linux AMI package repositories to apply automatically when
the instance boots using the AMI. If omitted, the default is
C<SECURITY>, which indicates that only security updates are applied. If
C<NONE> is specified, no updates are applied, and all updates must be
applied manually.

Valid values are: C<"SECURITY">, C<"NONE">

=head2 ScaleDownBehavior => Str

Specifies the way that individual Amazon EC2 instances terminate when
an automatic scale-in activity occurs or an instance group is resized.
C<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. C<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. C<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.

Valid values are: C<"TERMINATE_AT_INSTANCE_HOUR">, C<"TERMINATE_AT_TASK_COMPLETION">

=head2 SecurityConfiguration => Str

The name of a security configuration to apply to the cluster.


=head2 ServiceRole => Str

default value is C<1>. The maximum value is C<256>.


=head2 Steps => ArrayRef[L<Paws::EMR::StepConfig>]

A list of steps to run.

For Amazon EMR releases 3.x and 2.x. For Amazon EMR releases 4.x and
later, use Applications.

A list of strings that indicates third-party software to use. For more
information, see the Amazon EMR Developer Guide
(https://docs.aws.amazon.com/emr/latest/DeveloperGuide/emr-dg.pdf).
Currently supported values are:

=back


=head2 Tags => ArrayRef[L<Paws::EMR::Tag>]

A list of tags to associate with a cluster and propagate to Amazon EC2
instances.


=head2 VisibleToAllUsers => Bool

A value of C<true> indicates that all IAM users in the AWS account can
perform cluster actions if they have the proper IAM policy permissions.
This is the default. A value of C<false> indicates that only the IAM
user who created the cluster can perform actions.
