File is created in HDFS but can't write content

Question

• I Installed HDFP 3.0.1 in Vmware.
• DataNode and NameNode are running
• I upload files from AmbariUI/Terminal to HDFS, Everything works.

When I try to write the data:

    Configuration conf = new Configuration();
    conf.set("fs.defaultFS", "hdfs://172.16.68.131:8020");

    FileSystem fs = FileSystem.get(conf);
    OutputStream os = fs.create(new Path("hdfs://172.16.68.131:8020/tmp/write.txt"));
    InputStream is = new BufferedInputStream(new FileInputStream("/home/vq/hadoop/test.txt"));
    IOUtils.copyBytes(is, os, conf);

log:

It creates file in HDFS but it's empty.

The same is when I read the data:

    Configuration conf = new Configuration();
    conf.set("fs.defaultFS", "hdfs://172.16.68.131:8020");
    FileSystem fs = FileSystem.get(conf);
    FSDataInputStream inputStream = fs.open(new Path("hdfs://172.16.68.131:8020/tmp/ui.txt"));
    System.out.println(inputStream.available());
    byte[] bs = new byte[inputStream.available()];

I can read available bytes. but can't read the file.
