Hi，
In RoundRobinLoadBalancingSpi，according to the description of the document,per-task mode is the default configuration and should fit most of the use cases as it provides a fairly well-distributed split and also ensures that jobs within a single task are spread out across nodes to the maximum. But from the source code, global mode is the default value. I want to ask,does this belong to the document description issue, or is a bug?
