  39. def prioritize(blockManagerId: BlockManagerId, peers: Seq[BlockManagerId], peersReplicatedTo: HashSet[BlockManagerId], blockId: BlockId, numReplicas: Int): List[BlockManagerId]

    Method to prioritize a bunch of candidate peers of a block manager.

    Method to prioritize a bunch of candidate peers of a block manager. This implementation replicates the behavior of block replication in HDFS. For a given number of replicas needed, we choose a peer within the rack, one outside and remaining blockmanagers are chosen at random, in that order till we meet the number of replicas needed. This works best with a total replication factor of 3, like HDFS.

    blockManagerId

    Id of the current BlockManager for self identification

    peers

    A list of peers of a BlockManager

    peersReplicatedTo

    Set of peers already replicated to

    blockId

    BlockId of the block being replicated. This can be used as a source of randomness if needed.

    numReplicas

    Number of peers we need to replicate to

    returns

    A prioritized list of peers. Lower the index of a peer, higher its priority
