数据清理

1、 数据清理需求分析 
release_channel,device_id,city,device_id_type,app_ver_name 这几个字段如果缺失，则过滤 
将数据整成 字段,字段,字段,…… 这种形式 
在每条数据中添加一个字段：user_id（值就是mac) 
2、数据清理代码

public class AppLogClean {
    public static class MapTask extends Mapper<LongWritable, Text, Text, NullWritable> {
        StringBuilder sb = new StringBuilder();
        Text k = new Text();
        @Override
        protected void map(LongWritable key, Text value, Mapper<LongWritable, Text, Text, NullWritable>.Context context)
                throws IOException, InterruptedException {
            // 得到每行数据
            String line = value.toString();
            JSONObject ob1 = JSON.parseObject(line);
            JSONObject ob2 = ob1.getJSONObject("header");



            // 关键数据是否有丢失
            // release_channel,device_id,city,device_id_type,app_ver_name
            // 这几个字段如果缺失，则过滤
            if (StringUtils.isBlank(ob2.getString("release_channel"))
