Subject [jira] [Created] (BROOKLYN-212) Auto-scaling in finite BYON cluster keeps adding on-fire entities

----------------------------------

             Summary: Auto-scaling in finite BYON cluster keeps adding on-fire entities
                 Key: BROOKLYN-212
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-212
             Project: Brooklyn
          Issue Type: Bug
            Reporter: Aled Sage


When using a BYON location of a limited size (e.g. four vagrant VMs), if an auto-scaler policy
tries to resize above this number of VMs then it goes badly wrong!

Auto-scaling causes a new entity to be added to the cluster, but it fails to start because
the {{location.obtain()}} call fails. That entity is left in quarantine, on-fire.

The auto-scaler will then try again: another new entity is added, but this also fails. This
repeats, adding more and more entities.
