Peter Bacsko updated YUNIKORN-1337:
-----------------------------------
Description:
The problem was introduced by YUNIKORN-1205.
When the placeholders are running and the entire job is deleted, the
application won't perform a state transition from Accepted to Completing. The
reason is that there are still placeholder allocations, so
{{removeAsksInternal()}} will not trigger it.
On the other hand, when the allocations are removed, the innermost {{if}}
branch will not be taken:
{noformat}
if alloc.placeholder {
sa.allocatedPlaceholder =
resources.Sub(sa.allocatedPlaceholder, alloc.AllocatedResource)
// if all the placeholders are replaced, clear the placeholder
timer
if resources.IsZero(sa.allocatedPlaceholder) {
sa.clearPlaceholderTimer()
if (sa.IsCompleting() && sa.stateTimer == nil) ||
sa.IsFailing() || sa.IsResuming() {
... // this will be skipped
}
{noformat}
We have to check if there is no allocation left and then trigger a
{{CompleteApplication}} event.
