RunJobFlow creates and starts running a new cluster (job flow). The cluster runs the steps specified. After the steps complete, the cluster stops and the HDFS partition is lost. To prevent loss of data, configure the last step of the job flow to store results in Amazon S3. If the JobFlowInstancesConfig KeepJobFlowAliveWhenNoSteps parameter is set to TRUE, the cluster transitions to the WAITING state rather than shutting down after the steps have completed.

)[required] The name of the job flow.
The location in Amazon S3 to write the log files of the job flow. If a value is not provided, logs are not created.
The KMS key 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 releases 5.30.0 and later, excluding Amazon EMR 6.0.0.
A JSON string for selecting additional features.
Applies only to Amazon EMR AMI versions 3.x and 2.x. For Amazon EMR
releases 4.0 and later, ReleaseLabel is used. To specify a custom AMI,
use CustomAmiID.
The Amazon EMR release label, which determines the version of
open-source application packages installed on the cluster. Release
labels are in the form emr-x.x.x, where x.x.x is an Amazon EMR release
version such as 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/. The release
label applies only to Amazon EMR releases version 4.0 and later. Earlier
versions use AmiVersion.
[required] A specification of the number and type of Amazon EC2 instances.
A list of steps to run.
A list of bootstrap actions to run before Hadoop starts on the cluster nodes.
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. Currently supported values are:
"mapr-m3" - launch the job flow using MapR M3 Edition.
"mapr-m5" - launch the job flow using MapR M5 Edition.
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. Amazon 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. Supported values are:
"mapr-m3" - launch the cluster using MapR M3 Edition.
"mapr-m5" - launch the cluster using MapR M5 Edition.
"mapr" with the user arguments specifying "--edition,m3" or "--edition,m5" - launch the job flow using MapR M3 or M5 Edition respectively.
"mapr-m7" - launch the cluster using MapR M7 Edition.
"hunk" - launch the cluster with the Hunk Big Data Analytics Platform.
"hue"- launch the cluster with Hue installed.
"spark" - launch the cluster with Apache Spark installed.
"ganglia" - launch the cluster with the Ganglia Monitoring System installed.
Applies to Amazon EMR releases 4.0 and later. A case-insensitive list of applications for Amazon EMR to install and configure when launching the cluster. For a list of applications available for each Amazon EMR release version, see the Amazon EMRRelease Guide.
For Amazon EMR releases 4.0 and later. The list of configurations supplied for the Amazon EMR cluster that you are creating.
The VisibleToAllUsers parameter is no longer supported. By default, the
value is set to true. Setting it to false now has no effect.
Set this value to true so that IAM principals in the Amazon Web
Services account associated with the cluster can perform Amazon EMR
actions on the cluster that their IAM policies allow. This value
defaults to true for clusters created using the Amazon EMR API or the
CLI
create-cluster
command.
When set to false, only the IAM principal that created the cluster and
the Amazon Web Services account root user can perform Amazon EMR actions
for the cluster, regardless of the IAM permissions policies attached to
other IAM principals. For more information, see Understanding the Amazon EMR cluster VisibleToAllUsers setting
in the Amazon EMR Management Guide.
Also called instance profile and Amazon EC2 role. An IAM role for an
Amazon EMR cluster. The Amazon EC2 instances of the cluster assume this
role. The default role is EMR_EC2_DefaultRole. In order to use the
default role, you must have already created it using the CLI or console.
The IAM role that Amazon EMR assumes in order to access Amazon Web Services resources on your behalf. If you've created a custom service role path, you must specify it for the service role when you launch your cluster.
A list of tags to associate with a cluster and propagate to Amazon EC2 instances.
The name of a security configuration to apply to the cluster.
An IAM role for automatic scaling policies. The default role is
EMR_AutoScaling_DefaultRole. The IAM role provides permissions that
the automatic scaling feature requires to launch and terminate Amazon
EC2 instances in an instance group.
Specifies the way that individual Amazon EC2 instances terminate when an
automatic scale-in activity occurs or an instance group is resized.
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. 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.
TERMINATE_AT_TASK_COMPLETION available only in Amazon EMR releases
4.1.0 and later, and is the default for releases of Amazon EMR earlier
than 5.1.0.
Available only in Amazon EMR releases 5.7.0 and later. The ID of a
custom Amazon EBS-backed Linux AMI. If specified, Amazon EMR uses this
AMI when it launches cluster Amazon EC2 instances. For more information
about custom AMIs in Amazon EMR, see Using a Custom AMI
in the Amazon EMR Management Guide. If omitted, the cluster uses the
base Linux AMI for the ReleaseLabel specified. For Amazon EMR releases
2.x and 3.x, use AmiVersion instead.
For information about creating a custom AMI, see Creating an Amazon EBS-Backed Linux AMI in the Amazon Elastic Compute Cloud User Guide for Linux Instances. For information about finding an AMI ID, see Finding a Linux AMI.
The size, in GiB, of the Amazon EBS root device volume of the Linux AMI that is used for each Amazon EC2 instance. Available in Amazon EMR releases 4.x and later.
Applies only when 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 SECURITY,
which indicates that only security updates are applied. If NONE is
specified, no updates are applied, and all updates must be applied
manually.
Attributes for Kerberos configuration when Kerberos authentication is enabled using a security configuration. For more information see Use Kerberos Authentication in the Amazon EMR Management Guide.
Specifies the number of steps that can be executed concurrently. The
default value is 1. The maximum value is 256.
The specified managed scaling policy for an Amazon EMR cluster.
The specified placement group configuration for an Amazon EMR cluster.
Specifies a particular Amazon Linux release for all nodes in a cluster launch RunJobFlow request. If a release is not specified, Amazon EMR uses the latest validated Amazon Linux release for cluster launch.
