[jira] [Created] (YUNIKORN-2539) Add optional deadlock detection

Craig Condit created YUNIKORN-2539:
--------------------------------------

             Summary: Add optional deadlock detection
                 Key: YUNIKORN-2539
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-2539
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: core - scheduler, shim - kubernetes
            Reporter: Craig Condit
            Assignee: Craig Condit


We make heavy use of sync.Mutex and sync.RWMutex in our code. Unfortunately, while these are very performant, they can lead to difficult-to-diagnose deadlocks.

If we substitute our own locking routines, we can optionally enable deadlock detection. See [https://github.com/sasha-s/go-deadlock] for a possible solution.
