--------------------------------------
Summary: Soft Gang scheduling style is not working as expected
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
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
