> When task executor offer slot to job master, it will first mark the slot as active.
> If the offer slot call timeout, the task executor will try to call offerSlotsToJobManager again,
> but it will only offer the slot in ALLOCATED state. As the slot has already be mark ACTIVE, it will never be offered and this will cause slot leak.
