What's new and changed in IBM StreamSets

Cannot upgrade jobs if you are not the pipeline owner

• Issue: After you publish a pipeline, the UI does not let you upgrade a job to the latest pipeline version if you have access to both the pipeline and the job, but you are not the pipeline owner.
• Resolution: If you have access to both the pipeline and the job, you can upgrade a job to the latest pipeline version.

• When the preview record schema that is saved for a pipeline or fragment reaches an excessive size, Control Hub removes the saved schema when you publish, export, or upgrade the pipeline or fragment.

  Previously, a saved schema of excessive size caused a publish, export, or upgrade of the pipeline or fragment to fail.

• The scheduled task details page displays the ID of a scheduled task. You can use this ID to help identify the task.
