add_instance_fleet(cluster_id, instance_fleet)
add_instance_fleet(cluster_id, instance_fleet, params::Dict{String,<:Any})

Adds an instance fleet to a running cluster. The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x.

Arguments

• cluster_id: The unique identifier of the cluster.
• instance_fleet: Specifies the configuration of the instance fleet.

add_instance_groups(instance_groups, job_flow_id)
add_instance_groups(instance_groups, job_flow_id, params::Dict{String,<:Any})

Adds one or more instance groups to a running cluster.

Arguments

• instance_groups: Instance groups to add.
• job_flow_id: Job flow in which to add the instance groups.

add_job_flow_steps(job_flow_id, steps)
add_job_flow_steps(job_flow_id, steps, params::Dict{String,<:Any})

AddJobFlowSteps adds new steps to a running cluster. A maximum of 256 steps are allowed in each job flow. If your cluster 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 SSH 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, see Add More than 256 Steps to a Cluster in the Amazon EMR Management Guide. A step specifies the location of a JAR file stored either on the master node of the cluster 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. Amazon EMR 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 cluster that is in one of the following states: STARTING, BOOTSTRAPPING, RUNNING, or WAITING.

Arguments

• job_flow_id: A string that uniquely identifies the job flow. This identifier is returned by RunJobFlow and can also be obtained from ListClusters.
• steps: A list of StepConfig to be executed by the job flow.

Arguments

• block_public_access_configuration: A configuration for Amazon EMR block public access. The configuration applies to all clusters created in your account for the current Region. The configuration specifies whether block public access is enabled. If block public access is enabled, security groups associated with the cluster cannot have rules that allow inbound traffic from 0.0.0.0/0 or ::/0 on a port, unless the port is specified as an exception using PermittedPublicSecurityGroupRuleRanges in the BlockPublicAccessConfiguration.

run_job_flow(instances, name)
run_job_flow(instances, name, params::Dict{String,<:Any})

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. For additional protection, you can set the JobFlowInstancesConfig TerminationProtected parameter to TRUE to lock the cluster 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 cluster 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, see Add More than 256 Steps to a Cluster in the Amazon EMR Management Guide. For long running clusters, we recommend that you periodically store your results. The instance fleets configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions. The RunJobFlow request can contain InstanceFleets parameters or InstanceGroups parameters, but not both.

TERMINATEATINSTANCEHOUR 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. TERMINATEATTASKCOMPLETION 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. TERMINATEATTASK_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.
• "SecurityConfiguration": The name of a security configuration to apply to the cluster.
• "ServiceRole": The IAM role that will be assumed by the Amazon EMR service to access AWS resources on your behalf.
• "StepConcurrencyLevel": Specifies the number of steps that can be executed concurrently. The default value is 1. The maximum value is 256.
• "Steps": A list of steps to run.
• "SupportedProducts": 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.
• "Tags": A list of tags to associate with a cluster and propagate to Amazon EC2 instances.
• "VisibleToAllUsers": A value of 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 false indicates that only the IAM user who created the cluster can perform actions.

set_termination_protection(job_flow_ids, termination_protected)
set_termination_protection(job_flow_ids, termination_protected, params::Dict{String,<:Any})

SetTerminationProtection locks a cluster (job flow) so the 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 cluster is similar to calling the Amazon EC2 DisableAPITermination API on all EC2 instances in a cluster. SetTerminationProtection is used to prevent accidental termination of a cluster and to ensure that in the event of an error, the instances persist so that you can recover any data stored in their ephemeral instance storage. To terminate a cluster 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, seeManaging Cluster Termination in the Amazon EMR Management Guide.

Arguments

• job_flow_ids: A list of strings that uniquely identify the clusters to protect. This identifier is returned by RunJobFlow and can also be obtained from DescribeJobFlows .
• termination_protected: A Boolean that indicates whether to protect the cluster and prevent the Amazon EC2 instances in the cluster from shutting down due to API calls, user intervention, or job-flow error.

set_visible_to_all_users(job_flow_ids, visible_to_all_users)
set_visible_to_all_users(job_flow_ids, visible_to_all_users, params::Dict{String,<:Any})

Sets the ClusterVisibleToAllUsers value, which determines whether the cluster is visible to all IAM users of the AWS account associated with the cluster. Only the IAM user who created the cluster or the AWS account root user can call this action. The default value, true, indicates that all IAM users in the AWS account can perform cluster actions if they have the proper IAM policy permissions. If set to false, only the IAM user that created the cluster can perform actions. This action works on running clusters. You can override the default true setting when you create a cluster by using the VisibleToAllUsers parameter with RunJobFlow.

Arguments

• job_flow_ids: The unique identifier of the job flow (cluster).
• visible_to_all_users: A value of 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 false indicates that only the IAM user who created the cluster can perform actions.

start_notebook_execution(editor_id, execution_engine, relative_path, service_role)
start_notebook_execution(editor_id, execution_engine, relative_path, service_role, params::Dict{String,<:Any})

Starts a notebook execution.

Arguments

• editor_id: The unique identifier of the EMR Notebook to use for notebook execution.
• execution_engine: Specifies the execution engine (cluster) that runs the notebook execution.
• relative_path: The path and file name of the notebook file for this execution, relative to the path specified for the EMR Notebook. For example, if you specify a path of s3://MyBucket/MyNotebooks when you create an EMR Notebook for a notebook with an ID of e-ABCDEFGHIJK1234567890ABCD (the EditorID of this request), and you specify a RelativePath of mynotebookexecutions/notebookexecution.ipynb, the location of the file for the notebook execution is s3://MyBucket/MyNotebooks/e-ABCDEFGHIJK1234567890ABCD/mynotebookexecutions/notebookexecut ion.ipynb.
• service_role: The name or ARN of the IAM role that is used as the service role for Amazon EMR (the EMR role) for the notebook execution.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "NotebookExecutionName": An optional name for the notebook execution.
• "NotebookInstanceSecurityGroupId": The unique identifier of the Amazon EC2 security group to associate with the EMR Notebook for this notebook execution.
• "NotebookParams": Input parameters in JSON format passed to the EMR Notebook at runtime for execution.
• "Tags": A list of tags associated with a notebook execution. Tags are user-defined key-value pairs that consist of a required key string with a maximum of 128 characters and an optional value string with a maximum of 256 characters.

stop_notebook_execution(notebook_execution_id)
stop_notebook_execution(notebook_execution_id, params::Dict{String,<:Any})

Stops a notebook execution.

Arguments

• notebook_execution_id: The unique identifier of the notebook execution.

terminate_job_flows(job_flow_ids)
terminate_job_flows(job_flow_ids, params::Dict{String,<:Any})

TerminateJobFlows shuts a list of clusters (job flows) down. When a job flow is shut down, any step not yet completed is canceled and the EC2 instances on which the cluster is running are stopped. Any log files not already saved are uploaded to Amazon S3 if a LogUri was specified when the cluster was created. The maximum number of clusters allowed is 10. The call to TerminateJobFlows is asynchronous. Depending on the configuration of the cluster, it may take up to 1-5 minutes for the cluster to completely terminate and release allocated resources, such as Amazon EC2 instances.

Arguments

• job_flow_ids: A list of job flows to be shut down.

update_studio(studio_id)
update_studio(studio_id, params::Dict{String,<:Any})

Updates an Amazon EMR Studio configuration, including attributes such as name, description, and subnets.
