The identifier of the task runner. This value should be unique across your AWS account. In the case of AWS Data Pipeline Task Runner
            launched on a resource managed by AWS Data Pipeline, the web service provides a unique identifier when it launches the application. If you
            have written a custom task runner, you should assign a unique identifier for the task runner.
