question on replicate() in blockManager.scala

[rapelly kartheek]

Hi,

var cachedPeers: Seq[BlockManagerId] = null
  private def replicate(blockId: String, data: ByteBuffer, level:
StorageLevel) {
    val tLevel = StorageLevel(level.useDisk, level.useMemory,
level.deserialized, 1)
    if (cachedPeers == null) {
      cachedPeers = master.getPeers(blockManagerId, level.replication - 1)
    }
    for (peer: BlockManagerId <- cachedPeers) {
      val start = System.nanoTime
      data.rewind()
      logDebug("Try to replicate BlockId " + blockId + " once; The size of
the data is "
        + data.limit() + " Bytes. To node: " + peer)
      if (!BlockManagerWorker.syncPutBlock(PutBlock(blockId, data, tLevel),
        new ConnectionManagerId(peer.host, peer.port))) {
        logError("Failed to call syncPutBlock to " + peer)
      }
      logDebug("Replicated BlockId " + blockId + " once used " +
        (System.nanoTime - start) / 1e6 + " s; The size of the data is " +
        data.limit() + " bytes.")
    }


I get the flow of this code. But, I dont find any method being called for
actually writing the data into the set of peers chosen for replication.

Where exaclty is the replication happening?

Thank you!!
