[Update] Thanks for your continued feedback on this capability! Rest assured that we are tracking this request closely along with several other platform capabilities our customers have requested. In the meanwhile, you can leverage cluster scaling capability to adjust HDInsight cluster size according to your varying compute needs. Azure Data Factory is another option you can explore for scheduling jobs with automatic creation and deletion of clusters: https://azure.microsoft.com/en-us/documentation/articles/data-factory-data-transformation-activities/

Considering it has been over a year since Microsoft has commented on this issue, should we take that to mean that you have no interest in customers that refuse to keep their hadoop clusters up 24/7? Or is this significantly harder to accomplish than it appears on the surface?
