Cannot write HDFS from Java

[nilesim]

I used this repository to set up a hadoop cluster in Docker according to this tutorial. I have changed the docker-compose file to this because the versions in the tutorial are old.

These are the changes I made:
big-data-europe/docker-hadoop@master...nilesim:master

Now it is up and running and I can monitor it from http://localhost:9870/. 3 datanodes are up and running.

But when I try to write it from java with this code it gives error, creates the directory and file but could not write in it:

 public static void writeFileToHDFS() throws IOException {
        Configuration configuration = new Configuration();
        configuration.set("fs.defaultFS", "hdfs://localhost:9000");
        FileSystem fileSystem = FileSystem.get(configuration);
        //Create a path
        String fileName = "read_write_hdfs_example.txt";
        Path hdfsWritePath = new Path("/user/javadeveloperzone/javareadwriteexample/" + fileName);
        FSDataOutputStream fsDataOutputStream = fileSystem.create(hdfsWritePath,true);
        BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(fsDataOutputStream,StandardCharsets.UTF_8));
        bufferedWriter.write("Java API to write data in HDFS");
        bufferedWriter.newLine();
        bufferedWriter.close();
        fileSystem.close();
    }

repository:
(https://github.com/nsquare-jdzone/hadoop-examples/tree/master/ReadWriteHDFSExample)
from this tutorial:
https://javadeveloperzone.com/hadoop/java-read-write-files-hdfs-example/

and I monitored from (http://localhost:9870/explorer.html#/) that the directory and file is created when code run but size is 0 .
