             Summary: Memory leak in cache.Task: reference to old pod object is kept after update
                 Key: YUNIKORN-2319
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-2319
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: shim - kubernetes
            Reporter: Peter Bacsko

There is a memory leak in the shim: when the pod is updated, the old pod object is still referenced from Task, so the GC has no chance to remove it.
See screenshot: task points to version 80199, scheduler cache already has a newer version 81216.

We have two solutions:
1. Update the object in the Task together with the scheduler cache
2. Don't store the pointer to the pod, instead, always retrieve it from the scheduler cache
