前言
上次我们已经将MYSQL的数据传送到了HDFS，但是HDFS的数据没法直接进行查看和修改。这次我们将其转入hive仓库，并进行下一步的处理。
一、Hive on yarn
hive更换引擎
更换完成后，创建我们实验需要的数据库。
CREATE database medical;
二、数仓开发
为了实验方便我们现将之前的数据到删掉。
修改/opt/module/mock-medical/application.yml文件，统一时间。
修改 /opt/module/maxwell/config.properties
清空maxwell数据库
medical也清空
打开之前搭建的采集通道。
myhadoop.sh start
zk.sh start
kf.sh start
medical-f1.sh start
mxw.sh start
生成2023-05-01至2023-05-09的历史数据。
