hi, i am trying to figure out how hadoop uses data locality to schedule maps on nodes which locally store tha map input ... going through code i am going in circles in between a couple of file but not really getting anywhere ... that is to say that i cant locate the HDFS API or func that can communicate a node list that store replicas foe say a block!
i am going from FSNameSystem.java to DFSClient.java to BlocksWithLocations.java to DataNodeDescriptor.java and then back again without getting to the HDFS interface that communicates replicas' storing nodes for a block! someone plz help! momina
