[jira] [Created] (YUNIKORN-468) Node resource updates should trigger cleanup

Wilfred Spiegelenburg created YUNIKORN-468:
----------------------------------------------

             Summary: Node resource updates should trigger cleanup
                 Key: YUNIKORN-468
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-468
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: core - common
            Reporter: Wilfred Spiegelenburg


Updating a node can set the overall size of a node and the resources allocated by a different scheduler (co-existence). The core just updates the node size and currently stops scheduling new resources even when the node is over subscribed.

We should add a clean up in case that the node was shrunk and uses more than the resources available. the clean up should pre-empt enough resources to get it below the node size again.
