[jira] [Created] (YUNIKORN-1186) Race condition during recovery

Peter Bacsko created YUNIKORN-1186:
--------------------------------------

             Summary: Race condition during recovery
                 Key: YUNIKORN-1186
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1186
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: shim - kubernetes
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


The covery phase is not stable. Inside {{Context}}, we can create existing {{Application}} objects in two possible ways:

1. Asynchronously from shared informers. When Yunikorn starts up, it initializes the event handlers and it immediately receives the list of running pods and populates the {{Context}} from {{Manager.addPod()}}.

2. Synchronously from {{Manager.ListApplications()}}.

We have to make sure that these two calls do not interfere with each other and they create the same {{Application}} object, which right now does not seem to be the case.
