> After KYLIN-2655, we calculate the 'Interrupt time' when a job resumed from
> error/stopped status to give more accurate job duration time. However, when
> calculate the real duration time = 'Total time' - 'Interrupt time', we could
> get a negative value.
> The root cause is 'Interrupt time' calculated in
> DefaultChainedExecutable.onExecuteStart method. The 'Interrupt time' value is
> not only added with the true 'Interrupt time' when the job scheduled after
> resumed, but also increased when subsequent sub tasks executed.
