计算机毕业设计hadoop+spark+hive物流大数据分析平台 物流预测系统 物流信息爬虫 物流大数据 机器学习 深度学习 知识图谱 大数据

流程：
1.Python爬虫采集物流数据等存入mysql和.csv文件；
2.使用pandas+numpy或者MapReduce对上面的数据集进行数据清洗生成最终上传到hdfs；
3.使用hive数据仓库完成建库建表导入.csv数据集；
4.使用hive之hive_sql进行离线计算，使用spark之scala进行实时计算；
5.将计算指标使用sqoop工具导入mysql；
6.使用Flask+echarts进行可视化大屏实现、数据查询表格实现、含预测算法；

核心算法代码分享如下：
