[jira] [Created] (YUNIKORN-277) Support for auto-scaling phase 2

Wilfred Spiegelenburg created YUNIKORN-277:
----------------------------------------------

             Summary: Support for auto-scaling phase 2
                 Key: YUNIKORN-277
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-277
             Project: Apache YuniKorn
          Issue Type: Task
          Components: core - scheduler
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg
         Attachments: YuniKorn and cluster auto-scaler.pdf

YUNIKORN-231 added support for auto scaling updates with a number of limitations as described in the document: [^YuniKorn and cluster auto-scaler.pdf]

The change already improves the behaviour and limits the over provisioning of nodes in a big use case. The limitations however also mean that we still have some large gaps in the functionality:
- queue hierarchy support
- resource request changes over time
- support for non FIFO sorting policies
- resource fragmentation & reservation support

Not all these issues can or should be handled in one go.
