Chaoran Yu updated YUNIKORN-657:
--------------------------------
Description:
An application may fail for a number of reasons. For example,
* In gang scheduling, placeholders have expired before all of them can be
successfully allocated
* When no placement rules are defined (i.e. static queues are used), an
application is submitted to an non-existent queue
* The total amount of resources requested by a gang-scheduled app exceeds the
capacity of the queue
YK's the finite state machine has Failed as a terminal state of an app, meaning
that YK won't try to bring back a failed app ever again. The consequence is
that pods of such failed apps will be stuck in pending indefinitely. A better
behavior is for YK to mark those pods as failed too, while also passing the
reason of the failure to those pods.
