Hi list, I've come up against a scenario like this, to finish a same task, one of my hadoop cluster only needs 5 seconds, and another one needs more than 2 minutes. It's a common phenomenon that will decrease the parallelism of our system due to the faster one will wait the slower one. How to coordinate those nodes of different computing powers in a same cluster?
