Network.AWS.EMR.SetTerminationProtection

Contents

Description

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 in the Amazon Elastic MapReduce Developer's Guide.

See: AWS API Reference for SetTerminationProtection.

Synopsis

Creating a Request

setTerminationProtection Source

Creates a value of SetTerminationProtection with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Request Lenses

stpJobFlowIds :: Lens' SetTerminationProtection [Text] Source

A list of strings that uniquely identify the job flows to protect. This identifier is returned by RunJobFlow and can also be obtained from DescribeJobFlows .

stpTerminationProtected :: Lens' SetTerminationProtection Bool Source

A Boolean that indicates whether to protect the job flow and prevent the Amazon EC2 instances in the cluster from shutting down due to API calls, user intervention, or job-flow error.

Destructuring the Response

setTerminationProtectionResponse :: SetTerminationProtectionResponse Source

Creates a value of SetTerminationProtectionResponse with the minimum fields required to make a request.
