Review comment:
@cloud-fan This config can be set by users based on their setups. If
they are using AWS spot nodes, timeout can be set to somewhere around 120
seconds, if they are using fix duration 6hrs spot blocks (say they decommission
executors at 5:45), timeout can be set to 15 mins and so on.
If user doesn't set this timeout, things will remain as they were and tasks
running on decommission executors won't get any special treatment with respect
to speculation.
