Manikandan R updated YUNIKORN-2323:
-----------------------------------
Summary: Gang scheduling user experience issues (was: Soft Gang scheduling
style is not working as expected)
> Gang scheduling user experience issues
> --------------------------------------
>
> Key: YUNIKORN-2323
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2323
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - scheduler
> Affects Versions: 1.4.0
> Reporter: Manikandan R
> Assignee: Manikandan R
> Priority: Major
>
> For gang app, ResumeApplicationEvent would be set as part of
> timeoutPlaceholderProcessing process if needed. Which moves the app to
> running only when src is either new or accepted. A Gang App moves to the
> starting state once all placeholder ask have been added to the application.
> So, a situation wherein resume events trigger and doing the expected thing
> won't even arises. In addition, the app might have also transitioned into
> running state based on app start timer expiry (default is 5 mins). Without
> even being aware of current situations, timer moves the state to running
> which is not the right thing to do.
>
> Ideally, in the worst case, a gang app should continue to run as a normal app
> but given the above scenarios, it doesn't happen
