[jira] [Created] (YUNIKORN-582) Consider a fallback mechanism to schedule the app incase of gang failure instead of rejecting the app.

Ayub Pathan created YUNIKORN-582:
------------------------------------

             Summary: Consider a fallback mechanism to schedule the app incase of gang failure instead of rejecting the app.
                 Key: YUNIKORN-582
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-582
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - scheduler
            Reporter: Ayub Pathan


Incases when the app encounters gang issues due to placeholder pod allocation(failed due to various reasons), currently yunikorn marks the app failed. 

Instead, consider a configurable option for hard or soft gang scheduling which allows fallback mechanism to schedule the app successfully.  This needs to be brain stormed to see if this makes sense. Let us use this jira for documenting all the thoughts.
