      .setBlockPoolId(blockPoolId)
      .addAllBlockIds(Longs.asList(blockIds))
      .addAllTokens(tokensProtos)
      .build();
  // Send the RPC
  GetHdfsBlockLocationsResponseProto response;
  try {
    response = rpcProxy.getHdfsBlockLocations(NULL_CONTROLLER, request);
  } catch (ServiceException e) {
    throw ProtobufHelper.getRemoteException(e);

  List<byte[]> volumeIds = new ArrayList<byte[]>(volumeIdsByteStrings.size());
  for (ByteString bs : volumeIdsByteStrings) {
    volumeIds.add(bs.toByteArray());
  }
  // Array of indexes into the list of volumes, one per block
  List<Integer> volumeIndexes = response.getVolumeIndexesList();
  // Parsed HdfsVolumeId values, one per block
  return new HdfsBlocksMetadata(blockPoolId, blockIds,
