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

             Summary: cast failures are not handled correctly
                 Key: YUNIKORN-51
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-51
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: core - scheduler
            Reporter: Wilfred Spiegelenburg
         Attachments: cast_panic.go

While reviewing the code for YUNIKORN-47 I noticed that we are not correctly handling cast errors which could cause panics.
 In all cases we use the proper cast like this:
{code:java}
obj, ok := i.(*T)
{code}
We check the value of ok but do not handle the fact correctly that we can get a nil back which could cause a panic later when we us it.

examples: {{scheduler.processNodeEvent()}}

test code attached to show the issue.
