hdfs-parquet-scanner's verification of file version is not correct

HdfsParquetScanner::ProcessFooter() {

if (memcmp(magic_number_ptr,
      PARQUET_VERSION_NUMBER, sizeof(PARQUET_VERSION_NUMBER) != 0)) { <-- paren in wrong place, not comparing the right number of bytes.
    return Status(Substitute("File $0 is invalid.  Invalid file footer: $1",
        stream_->filename(),
        string((char*)magic_number_ptr, sizeof(PARQUET_VERSION_NUMBER))));
