我想设计一个web项目，当用户上传文件到hadoophdfs时，用户可以通过web看到自己的上传状态。有简单的javaapi吗？
有人能帮忙吗？
现在我只知道如何使用api将文件上传到hdfs。

public synchronized static void upload(FileSystem fs, String local,
        String remote) {
    // Path home = fs.getHomeDirectory();
    Path workDir = fs.getWorkingDirectory();
    Path dst = new Path(workDir + "/" + remote);
    Path src = new Path(local);
    try {
        fs.copyFromLocalFile(false, true, src, dst);
        log.info("upload " + local + " to  " + remote + " successed. ");
    } catch (Exception e) {
        log.error("upload " + local + " to  " + remote + " failed :"
                + ExceptionUtils.getFullStackTrace(e));
    }
}
