Hey Vinod, On the most part I have indeed observed this to be the case. However every now and then the tasks are being launched out of order. Here's a slave log https://gist.github.com/tarnfeld/7a275e2ddffdc4da9e2f.
You can see the slave is assigned the tasks in order, *Task_Tracker_10* first then *slots_Task_Tracker_10* which is the order they should be. Though they are queued for launching by the executor in the wrong order.
