To launch the job flow in Amazon VPC, set this parameter to the identifier of the Amazon VPC subnet where you want the job flow to launch. If you do not specify this value, the job flow is launched in the normal AWS cloud, outside of a VPC.
Amazon VPC currently does not support cluster compute quadruple extra large (cc1.4xlarge) instances. Thus, you cannot specify the cc1.4xlarge instance type for nodes of a job flow launched in a VPC.
Ec2AvailabilityZone (string) --
The Availability Zone in which the cluster will run.
IamInstanceProfile (string) --
The IAM role that was specified when the job flow was launched. The EC2 instances of the job flow assume this role.

AutoTerminate (boolean) --
Specifies whether the cluster should terminate after completing all steps.
TerminationProtected (boolean) --
Indicates whether Amazon EMR will lock the cluster to prevent the EC2 instances from being terminated by an API call or user intervention, or in the event of a cluster error.
VisibleToAllUsers (boolean) --
Indicates whether the job flow is visible to all IAM users of the AWS account associated with the job flow. If this value is set to true, all IAM users of that AWS account can view and manage the job flow if they have the proper policy permissions set. If this value is false, only the IAM user that created the cluster can view and manage it. This value can be changed using the SetVisibleToAllUsers action.
Applications (list) --
The applications installed on this cluster.
(dict) --
An application is any Amazon or third-party software that you can add to the cluster. This structure contains a list of strings that indicates the software to use with the cluster and accepts a user argument list. Amazon EMR accepts and forwards the argument list to the corresponding installation script as bootstrap action argument. For more information, see Launch a Job Flow on the MapR Distribution for Hadoop. Currently supported values are:
"mapr-m3" - launch the job flow using MapR M3 Edition.
"mapr-m5" - launch the job flow using MapR M5 Edition.

(string) --
(string) --
Tags (list) --
A list of tags associated with a cluster.
(dict) --
A key/value pair containing user-defined metadata that you can associate with an Amazon EMR resource. Tags make it easier to associate clusters in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tagging Amazon EMR Resources.
Key (string) --
A user-defined key, which is the minimum required information for a valid tag. For more information, see Tagging Amazon EMR Resources.
Value (string) --

ServiceRole (string) --
The IAM role that will be assumed by the Amazon EMR service to access AWS resources on your behalf.
NormalizedInstanceHours (integer) --
An approximation of the cost of the job flow, represented in m1.small/hours. This value is incremented one time for every hour an m1.small instance runs. Larger instances are weighted more, so an EC2 instance that is roughly four times more expensive would result in the normalized instance hours being incremented by four. This result is only an approximation and does not reflect the actual billing rate.
MasterPublicDnsName (string) --
The public DNS name of the master EC2 instance.
Configurations (list) --
The list of Configurations supplied to the EMR cluster.
(dict) --
Specifies a hardware and software configuration of the EMR cluster. This includes configurations for applications and software bundled with Amazon EMR. The Configuration object is a JSON object which is defined by a classification and a set of properties. Configurations can be nested, so a configuration may have its own Configuration objects listed.

Properties (dict) --
A set of properties supplied to the Configuration object.

{'SecurityConfiguration': 'string'}
RunJobFlow creates and starts running a new job flow. The job flow will run the steps specified. Once the job flow completes, the cluster is stopped 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 job flow will transition to the WAITING state rather than shutting down once the steps have completed.
For additional protection, you can set the JobFlowInstancesConfig TerminationProtected parameter to TRUE to lock the job flow and prevent it from being terminated by API call, user intervention, or in the event of a job flow error.
A maximum of 256 steps are allowed in each job flow.
If your job flow is long-running (such as a Hive data warehouse) or complex, you may require more than 256 steps to process your data. You can bypass the 256-step limitation in various ways, including using the SSH shell to connect to the master node and submitting queries directly to the software running on the master node, such as Hive and Hadoop. For more information on how to do this, go to Add More than 256 Steps to a Job Flow in the Amazon Elastic MapReduce Developer's Guide.
For long running job flows, we recommend that you periodically store your results.
