[Demo_03] MapReduce 实现多类型输出

// 多输出格式设置
MultipleOutputs.addNamedOutput(job, "text", TextOutputFormat.class, Text.class, IntWritable.class);
MultipleOutputs.addNamedOutput(job, "seq", SequenceFileOutputFormat.class, Text.class, DoubleWritable.class);

// 写入文件
mos.write("text", new Text(year), new IntWritable(temp),"E:/test/wc/text_out");
mos.write("seq", key, new DoubleWritable(max / 10.0), "E:/test/wc/seq_out");
