> When use Spark with dynamic allocation, we set idle time to 5s
> We always got exception about neety 'Connect reset by peers'
>
> I suspect that it's because we set idle time 5s is too small, it will cause
> when Blockmanager call netty io, the executor has been remove because of
> timeout.
> But not timely notify driver's BlocakManager
