是的，这是可能的- checkout 序列FileWriter。请参见下面的代码示例，该示例将集群数据点写入文件。以下是一篇博客文章，详细描述了这一点：

public static void writePointsToFile(List<Vector> points,
                                     String fileName,
                                     FileSystem fs,
                                     Configuration conf) throws IOException {
    Path path = new Path(fileName);
    SequenceFile.Writer writer = new SequenceFile.Writer(fs, conf,
            path, LongWritable.class, VectorWritable.class);
    long recNum = 0;
    VectorWritable vec = new VectorWritable();
    for (Vector point : points) {
        vec.set(point);
        writer.append(new LongWritable(recNum++), vec);
    }
    writer.close();
}
