Does spark guarantee to push the processing to the data ? Before creating tasks does spark always check for data location ? So for example if I have 3 spark nodes (Node1, Node2, Node3) and data is local to just 2 nodes (Node1 and Node2) , will spark always schedule tasks on the node for which the data is local ie Node1 and Node 2(assuming Node1 and Node2 have enough resources to execute the tasks)?
