"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.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/awserr"
	"github.com/aws/aws-sdk-go/aws/awsutil"
	"github.com/aws/aws-sdk-go/service/emr"

	if err != nil {
		if awsErr, ok := err.(awserr.Error); ok {
			// Generic AWS Error with Code, Message, and original error (if any)
			fmt.Println(awsErr.Code(), awsErr.Message(), awsErr.OrigErr())

}

Output:

func (*EMR) AddInstanceGroupsRequest 

func (c *EMR) AddInstanceGroupsRequest(input *AddInstanceGroupsInput) (req *aws.Request, output *AddInstanceGroupsOutput)

AddInstanceGroupsRequest generates a request for the AddInstanceGroups operation.

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) AddTags 

func (c *EMR) AddTags(input *AddTagsInput) (*AddTagsOutput, error)

DescribeJobFlows returns a list of job flows that match all of the supplied

parameters. The parameters can include a list of job flow IDs, job flow states, and restrictions on job flow creation date and time. 

Regardless of supplied parameters, only job flows created within the last

func (*EMR) RemoveTags 

func (c *EMR) RemoveTags(input *RemoveTagsInput) (*RemoveTagsOutput, error)

Removes tags from 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 (http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-plan-tags.html).

The following example removes the stack tag with value Prod from a cluster:

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/awserr"

}

Output:

func (*EMR) RemoveTagsRequest 

func (c *EMR) RemoveTagsRequest(input *RemoveTagsInput) (req *aws.Request, output *RemoveTagsOutput)

RemoveTagsRequest generates a request for the RemoveTags operation.

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.

Output:

func (*EMR) RunJobFlowRequest 

func (c *EMR) RunJobFlowRequest(input *RunJobFlowInput) (req *aws.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.

func (*EMR) SetVisibleToAllUsers 

func (c *EMR) SetVisibleToAllUsers(input *SetVisibleToAllUsersInput) (*SetVisibleToAllUsersOutput, error)

Sets whether all AWS Identity and Access Management (IAM) users under your account can access the specified job flows. This action works on running job flows. 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.

Example 
package main

import (
	"fmt"

Output:

func (*EMR) SetVisibleToAllUsersRequest 

func (c *EMR) SetVisibleToAllUsersRequest(input *SetVisibleToAllUsersInput) (req *aws.Request, output *SetVisibleToAllUsersOutput)

SetVisibleToAllUsersRequest generates a request for the SetVisibleToAllUsers operation.

func (*EMR) TerminateJobFlows 

func (c *EMR) TerminateJobFlows(input *TerminateJobFlowsInput) (*TerminateJobFlowsOutput, error)

TerminateJobFlows shuts a list of job flows down. When a job flow is shut down, any step not yet completed is canceled and the EC2 instances on which the job flow is running are stopped. 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.

Example 
package main

import (
