EMR Cluster - Automatically apply latest Amazon Linux Updates - is there an API call for setting updates

Hi, If I understand your question correctly, the Automatically apply latest Amazon Linux updates in Console will map to the attribute osReleaseLabel in RunJobFlow API. When this option is checked in Console, osReleaseLabel won't be set, so EMR will use the latest validated Amazon Linux release for cluster launch. Whereas, when the option is unchecked and a specific AMI release is specified, the osReleaseLabel will be set and EMR will launch instances using the provided AMI release. Similarly, DescribeCluster API can be used to verify if this attribute was set or not.
