AWS SDK for PHP 3.x

Service ID: elasticmapreduce

Version: 2009-03-31

This page describes the parameters and results for the operations of the Amazon Elastic MapReduce (2009-03-31), and shows how to use the Aws\Emr\EmrClient object to call the described operations. This documentation is specific to the 2009-03-31 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

DescribeJobFlows
ListBootstrapActions
ListClusters
ListInstanceFleets
ListInstanceGroups
ListInstances
ListSteps

Waiters

Waiters allow you to poll a resource until it enters into a desired state. A waiter has a name used to describe what it does, and is associated with an API operation. When creating a waiter, you can provide the API operation parameters associated with the corresponding operation. Waiters can be accessed using the getWaiter($waiterName, $operationParameters) method of a client object. This client supports the following waiters:

Waiter name	API Operation	Delay	Max Attempts
ClusterRunning	DescribeCluster	30	60
StepComplete	DescribeStep	30	60
ClusterTerminated	DescribeCluster	30	60

AddJobFlowSteps

$result = $client->addJobFlowSteps([/* ... */]);
$promise = $client->addJobFlowStepsAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->addJobFlowSteps([
    'JobFlowId' => '<string>', // REQUIRED
    'Steps' => [ // REQUIRED

DescribeJobFlows

$result = $client->describeJobFlows([/* ... */]);
$promise = $client->describeJobFlowsAsync([/* ... */]);

This API is deprecated and will eventually be removed. We recommend you use ListClusters, DescribeCluster, ListSteps, ListInstanceGroups and ListBootstrapActions instead.

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 two months are returned.

If no parameters are supplied, then job flows matching either of the following criteria are returned:

Job flows created and completed in the last two weeks
Job flows created within the last two months that are in one of the following states: RUNNING, WAITING, SHUTTING_DOWN, STARTING

Amazon EMR can return a maximum of 512 job flow descriptions.

Parameter Syntax

$result = $client->describeJobFlows([
    'CreatedAfter' => <integer || string || DateTime>,
    'CreatedBefore' => <integer || string || DateTime>,
    'JobFlowIds' => ['<string>', ...],
    'JobFlowStates' => ['<string>', ...],
]);

RemoveTags

$result = $client->removeTags([/* ... */]);
$promise = $client->removeTagsAsync([/* ... */]);

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 Tag Clusters.

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

Parameter Syntax

$result = $client->removeTags([
    'ResourceId' => '<string>', // REQUIRED
    'TagKeys' => ['<string>', ...], // REQUIRED
]);

Parameter Details

Members

ResourceId

Type: string

The Amazon EMR resource identifier from which tags will be removed. This value must be a cluster identifier.

TagKeys

Type: Array of strings

A list of tag keys to remove from a resource.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

InternalServerException:
This exception occurs when there is an internal failure in the EMR service.
InvalidRequestException:
This exception occurs when there is something wrong with user input.

RunJobFlow

$result = $client->runJobFlow([/* ... */]);
$promise = $client->runJobFlowAsync([/* ... */]);

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.

]

Result Details

Members

JobFlowId

Type: string

An unique identifier for the job flow.

Errors

InternalServerError:
Indicates that an error occurred while processing the request and that the request was not completed.

SetTerminationProtection

$result = $client->setTerminationProtection([/* ... */]);
$promise = $client->setTerminationProtectionAsync([/* ... */]);

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.

TerminateJobFlows

$result = $client->terminateJobFlows([/* ... */]);
$promise = $client->terminateJobFlowsAsync([/* ... */]);

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.

TargetOnDemandCapacity

Type: int

The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision. When the instance fleet launches, Amazon EMR tries to provision On-Demand instances as specified by InstanceTypeConfig. Each instance configuration has a specified WeightedCapacity. When an On-Demand instance is provisioned, the WeightedCapacity units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedOnDemandCapacity to determine the Spot capacity units that have been provisioned for the instance fleet.

If not specified or set to 0, only Spot instances are provisioned for the instance fleet using TargetSpotCapacity. At least one of TargetSpotCapacity and TargetOnDemandCapacity should be greater than 0. For a master instance fleet, only one of TargetSpotCapacity and TargetOnDemandCapacity can be specified, and its value must be 1.

TargetSpotCapacity

Type: int

The target capacity of Spot units for the instance fleet, which determines how many Spot instances to provision. When the instance fleet launches, Amazon EMR tries to provision Spot instances as specified by InstanceTypeConfig. Each instance configuration has a specified WeightedCapacity. When a Spot instance is provisioned, the WeightedCapacity units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedSpotCapacity to determine the Spot capacity units that have been provisioned for the instance fleet.

If not specified or set to 0, only On-Demand instances are provisioned for the instance fleet. At least one of TargetSpotCapacity and TargetOnDemandCapacity should be greater than 0. For a master instance fleet, only one of TargetSpotCapacity and TargetOnDemandCapacity can be specified, and its value must be 1.

SimpleScalingPolicyConfiguration

Description

An automatic scaling configuration, which describes how the policy adds or removes instances, the cooldown period, and the number of EC2 instances that will be added each time the CloudWatch metric alarm condition is satisfied.

Members

AdjustmentType

Type: string

The way in which EC2 instances are added (if ScalingAdjustment is a positive number) or terminated (if ScalingAdjustment is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment, which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment, which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment, which should be expressed as a positive integer.

CoolDown

Type: int

The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.

ScalingAdjustment

Type: int

The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.

SpotProvisioningSpecification

Description

The launch specification for Spot instances in the instance fleet, which determines the defined duration and provisioning timeout behavior.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Members

BlockDurationMinutes

Type: int

The defined duration for Spot instances (also known as Spot blocks) in minutes. When specified, the Spot instance does not terminate before the defined duration expires, and defined duration pricing for Spot instances applies. Valid values are 60, 120, 180, 240, 300, or 360. The duration period starts as soon as a Spot instance receives its instance ID. At the end of the duration, Amazon EC2 marks the Spot instance for termination and provides a Spot instance termination notice, which gives the instance a two-minute warning before it terminates.

TimeoutAction

Type: string

The action to take when TargetSpotCapacity has not been fulfilled when the TimeoutDurationMinutes has expired. Spot instances are not uprovisioned within the Spot provisioining timeout. Valid values are TERMINATE_CLUSTER and SWITCH_TO_ON_DEMAND. SWITCH_TO_ON_DEMAND specifies that if no Spot instances are available, On-Demand Instances should be provisioned to fulfill any remaining Spot capacity.

TimeoutDurationMinutes

Type: int

The spot provisioning timeout period in minutes. If Spot instances are not provisioned within this time period, the TimeOutAction is taken. Minimum value is 5 and maximum value is 1440. The timeout applies only during initial provisioning, when the cluster is first created.
