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 (http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-mapr.html). Currently supported values are:
"mapr-m3" - launch the job flow using MapR M3 Edition. "mapr-m5" - launch
the job flow 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. In Amazon EMR releases 4.0 and greater, the only accepted parameter is the application name. To pass arguments to applications, you supply a configuration for each application.

type EMR ¶
Amazon Elastic MapReduce (Amazon EMR) is a web service that makes it easy to process large amounts of data efficiently. Amazon EMR uses Hadoop processing combined with several AWS products to do tasks such as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehousing. The service client's operations are safe to be used concurrently. It is not safe to mutate any of the client's properties though.

func (*EMR) AddJobFlowSteps ¶
func (c *EMR) AddJobFlowSteps(input *AddJobFlowStepsInput) (*AddJobFlowStepsOutput, error)
AddJobFlowSteps adds new steps to a running job flow. 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 (http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/AddMoreThan256Steps.html) in the Amazon Elastic MapReduce Developer's Guide.
A step specifies the location of a JAR file stored either on the master
node of the job flow or in Amazon S3. Each step is performed by the main function of the main class of the JAR file. The main class can be specified either in the manifest of the JAR or by using the MainFunction parameter of the step.
Elastic MapReduce executes each step in the order listed. For a step to
be considered complete, the main function must exit with a zero exit code and all Hadoop jobs started while the step was running must have completed and run successfully.
You can only add steps to a job flow that is in one of the following states:
STARTING, BOOTSTRAPPING, RUNNING, or WAITING.
func (*EMR) AddJobFlowStepsRequest ¶

func (*EMR) RunJobFlow ¶
func (c *EMR) RunJobFlow(input *RunJobFlowInput) (*RunJobFlowOutput, error)
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 (http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/AddMoreThan256Steps.html) in the Amazon Elastic MapReduce Developer's Guide.
For long running job flows, we recommend that you periodically store your results.

func (c *EMR) RunJobFlowRequest(input *RunJobFlowInput) (req *request.Request, output *RunJobFlowOutput)
RunJobFlowRequest generates a request for the RunJobFlow operation.
func (*EMR) SetTerminationProtection ¶
func (c *EMR) SetTerminationProtection(input *SetTerminationProtectionInput) (*SetTerminationProtectionOutput, error)
SetTerminationProtection locks a job flow so the Amazon EC2 instances in the cluster cannot be terminated by user intervention, an API call, or in the event of a job-flow error. The cluster still terminates upon successful completion of the job flow. Calling SetTerminationProtection on a job flow is analogous to calling the Amazon EC2 DisableAPITermination API on all of the EC2 instances in a cluster.
SetTerminationProtection is used to prevent accidental termination of a
job flow and to ensure that in the event of an error, the instances will persist so you can recover any data stored in their ephemeral instance storage.
To terminate a job flow that has been locked by setting SetTerminationProtection
to true, you must first unlock the job flow by a subsequent call to SetTerminationProtection in which you set the value to false.
For more information, go to Protecting a Job Flow from Termination (http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/UsingEMR_TerminationProtection.html)
in the Amazon Elastic MapReduce Developer's Guide.

You can also set the visibility of a job flow when you launch it using the VisibleToAllUsers parameter of RunJobFlow. The SetVisibleToAllUsers action can be called only by an IAM user who created the job flow or the AWS account that owns the job flow.
func (*EMR) SetVisibleToAllUsersRequest ¶
func (c *EMR) SetVisibleToAllUsersRequest(input *SetVisibleToAllUsersInput) (req *request.Request, output *SetVisibleToAllUsersOutput)
SetVisibleToAllUsersRequest generates a request for the SetVisibleToAllUsers operation.
func (*EMR) TerminateJobFlows ¶
func (c *EMR) TerminateJobFlows(input *TerminateJobFlowsInput) (*TerminateJobFlowsOutput, error)

Any log files not already saved are uploaded to Amazon S3 if a LogUri was specified when the job flow was created.
The maximum number of JobFlows allowed is 10. The call to TerminateJobFlows
is asynchronous. Depending on the configuration of the job flow, it may take up to 5-20 minutes for the job flow to completely terminate and release allocated resources, such as Amazon EC2 instances.
func (*EMR) TerminateJobFlowsRequest ¶
func (c *EMR) TerminateJobFlowsRequest(input *TerminateJobFlowsInput) (req *request.Request, output *TerminateJobFlowsOutput)
