MapReduce自定义类设置中文属性写出到HDFS乱码

自定义类中重写write和readFields方法

@Override
public void write(DataOutput out) throws IOException {
    out.writeUTF(this.name);
    out.writeUTF(this.course);
}

@Override
public void readFields(DataInput in) throws IOException {
    this.name = in.readUTF();
    this.course = in.readUTF();
}

map方法中设置中文属性值

@Override
protected void map(LongWritable key, Text value, Context context) throws IOException, InterruptedException {
    String[] split = value.toString().split("\t");
    if (split.length == 6) {
        k.setName(split[0]);
        k.setCourse("语文");
        v.set(Double.parseDouble(split[3].trim()));
        context.write(k, v);
        k.setCourse("数学");
        v.set(Double.parseDouble(split[4].trim()));
        context.write(k, v);
        k.setCourse("英语");
