The only way to stop a HA job is to > actually cancel it. Therefore the configured clean up behaviour doesn't > matter. > In case of non-HA, suspensions happen because of graceful shut down (for > example stopping a YARN session). In this case I would treat the clean up > behaviour similar to cancelling the job. > {code} > ExternalizedCheckpointCleanup.DELETE_ON_CANCELLATION => delete on suspension > ExternalizedCheckpointCleanup.RETAIN_ON_CANCELLATION => retain on suspension > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
