AWS Amazon EMR CLI Commands

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

Adds one or more instance groups to a running cluster.

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, incl

Adds tags to an Amazon EMR resource, such as a cluster or an Amazon EMR Studio. Tags make it easier to associate resources in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters.

Cancels a pending step or steps in a running cluster. Available only in Amazon EMR versions 4.8.0 and later, excluding version 5.0.0. A maximum of 256 steps are allowed in each CancelSteps request. CancelSteps is idempotent but asynchronous; it does not guarantee that a step will be canceled, even i

Provides information about the bootstrap actions associated with a cluster.

Provides the status of all clusters visible to this Amazon Web Services account. Allows you to filter the list of clusters based on certain criteria; for example, filtering by cluster creation date and time or by status. This call returns a maximum of 50 clusters in unsorted order per call, but retu

Lists all available details about the instance fleets in a cluster. The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.

Provides all available details about the instance groups in a cluster.

Provides information for all active Amazon EC2 instances and Amazon EC2 instances terminated in the last 30 days, up to a maximum of 2,000. Amazon EC2 instances in any of the following states are considered active: AWAITING_FULFILLMENT, PROVISIONING, BOOTSTRAPPING, RUNNING.

Provides summaries of all notebook executions. You can filter the list based on multiple criteria such as status, time range, and editor id. Returns a maximum of 50 notebook executions and a marker to track the paging of a longer notebook execution list across multiple ListNotebookExecutions calls.

Retrieves release labels of Amazon EMR services in the Region where the API is called.

Lists all the security configurations visible to this account, providing their creation dates and times, and their names. This call returns a maximum of 50 clusters per call, but returns a marker to track the paging of the cluster list across multiple ListSecurityConfigurations calls.

Provides a list of steps for the cluster in reverse order unless you specify stepIds with the request or filter by StepStates. You can specify a maximum of 10 stepIDs. The CLI automatically paginates results to return a list greater than 50 steps. To return more than 50 steps using the CLI, specify

Returns a list of all user or group session mappings for the Amazon EMR Studio specified by StudioId.

Returns a list of all Amazon EMR Studios associated with the Amazon Web Services account. The list includes details such as ID, Studio Access URL, and creation time for each Studio.

A list of the instance types that Amazon EMR supports. You can filter the list by Amazon Web Services Region and Amazon EMR release.

Modifies the number of steps that can be executed concurrently for the cluster specified using ClusterID.

Modifies the target On-Demand and target Spot capacities for the instance fleet with the specified InstanceFleetID within the cluster specified using ClusterID. The call either succeeds or fails atomically. The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, e

ModifyInstanceGroups modifies the number of nodes and configuration settings of an instance group. The input parameters include the new target instance count for the group and the instance group ID. The call will either succeed or fail atomically.

Creates or updates an automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates Amazon EC2 instances in response to the value of a CloudWatch metric.

Auto-termination is supported in Amazon EMR releases 5.30.0 and 6.1.0 and later. For more information, see Using an auto-termination policy. Creates or updates an auto-termination policy for an Amazon EMR cluster. An auto-termination policy defines the amount of idle time in seconds after which a

Creates or updates an Amazon EMR block public access configuration for your Amazon Web Services account in the current Region. For more information see Configure Block Public Access for Amazon EMR in the Amazon EMR Management Guide.

Creates or updates a managed scaling policy for an Amazon EMR cluster. The managed scaling policy defines the limits for resources, such as Amazon EC2 instances that can be added or terminated from a cluster. The policy only applies to the core and task nodes. The master node cannot be scaled after

Removes an automatic scaling policy from a specified instance group within an Amazon EMR cluster.

Removes an auto-termination policy from an Amazon EMR cluster.

Removes a managed scaling policy from a specified Amazon EMR cluster.

Removes tags from an Amazon EMR resource, such as a cluster or Amazon EMR Studio. Tags make it easier to associate resources in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters. The following example removes the stack

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 JobFlowInstancesCon

You can use the SetKeepJobFlowAliveWhenNoSteps to configure a cluster (job flow) to terminate after the step execution, i.e., all your steps are executed. If you want a transient cluster that shuts down after the last of the current executing steps are completed, you can configure SetKeepJobFlowAliv

SetTerminationProtection locks a cluster (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 c

Specify whether to enable unhealthy node replacement, which lets Amazon EMR gracefully replace core nodes on a cluster if any nodes become unhealthy. For example, a node becomes unhealthy if disk usage is above 90%. If unhealthy node replacement is on and TerminationProtected are off, Amazon EMR imm

The SetVisibleToAllUsers parameter is no longer supported. Your cluster may be visible to all users in your account. To restrict cluster access using an IAM policy, see Identity and Access Management for Amazon EMR. Sets the Cluster$VisibleToAllUsers value for an Amazon EMR cluster. When true, IA

Starts a notebook execution.

Stops a notebook execution.

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 Amazon EC2 instances on which the cluster is running are stopped.
