   */
public long createFile(Path path, int numBlocks, CreateOpts... options) throws IOException {
    BlockSize blockSizeOpt = CreateOpts.getOpt(CreateOpts.BlockSize.class, options);
    long blockSize = blockSizeOpt != null ? blockSizeOpt.getValue() : DEFAULT_BLOCK_SIZE;
    FSDataOutputStream out = create(path, EnumSet.of(CreateFlag.CREATE), options);
    byte[] data = getFileData(numBlocks, blockSize);
    out.write(data, 0, data.length);
    out.close();
