Prabhu Joseph commented on YARN-9790:
-------------------------------------
[~kyungwan nam] Default app lifetime will be used when app does not specify the
lifetime. Max app lifetime is used to limit the user specified lifetime. If we
set Default to some value and Max to -1, then there is no limit and so any user
can specify any higher lifetime. The below check is needed to prevent the same.
{code}
if (defaultApplicationLifetime > maxApplicationLifetime) {
{code}
Check {{CapacityScheduler#checkAndGetApplicationLifetime}} which considers max
is > default and does limit on user specified lifetime.
> Failed to set default-application-lifetime if maximum-application-lifetime is
> less than or equal to zero
