CancelJob - AWS Batch

CancelJob

Cancels a job in an AWS Batch job queue. Jobs that are in a SUBMITTED, PENDING, or RUNNABLE state are cancelled and the job status is updated to FAILED.

Note

A PENDING job is canceled after all dependency jobs are completed. Therefore, it may take longer than expected to cancel a job in PENDING status.

When you try to cancel an array parent job in PENDING, AWS Batch attempts to cancel all child jobs. The array parent job is canceled when all child jobs are completed.

Jobs that progressed to the STARTING or RUNNING state aren't canceled. However, the API operation still succeeds, even if no job is canceled. These jobs must be terminated with the TerminateJob operation.

If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.

Errors

ClientException

These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.

HTTP Status Code: 400

ServerException

These errors are usually caused by a server issue.

Examples

In the following example or examples, the Authorization header contents ( [authorization-params] ) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

Example

This example cancels a job with the specified job ID.
