dolphinscheduler 3.0.1数据质量

🐬环境配置
🐬定义质量节点测试
- 🐠运行失败
🐬源码

🔼上一集：dolphinscheduler 3.0.1 资源中心

*️⃣主目录：dolphinscheduler 3.0.1功能梳理及源码解读

🔽下一集：dolphinscheduler 3.0.1 数据源中心

🐬环境配置

/worker-server/conf/dolphinscheduler_env.sh
- SPARK_HOME2 ：配置spark安装目录
- HADOOP_USER_NAME：增加该变量，填写hadoop集群的部署用户(HADOOP_HOME等不需要配置，目前我是没遇到过)
```
org.apache.hadoop.security.AccessControlException): Permission denied: user=dolphin, access=WRITE
```
/worker-server/conf/common.properties
- data-quality.jar.name=dolphinscheduler-data-quality-3.0.1-SNAPSHOT.jar :保持jar包名称和编译后的名称一致，默认为dolphinscheduler-data-quality-dev-SNAPSHOT.jar
给执行租户赋权，添加hadoop部署用户组，比如租户dolphin,hadoop部署用户组为bigdata
```
sudo usermod -a -G bigdata dolphin
```

🐬定义质量节点测试

直接对着官网操作吧，最开始官网资料还没有3.0，后来就不看了，貌似多走了一些路。

校验公式：[校验方式][操作符][阈值]，如果结果为真，则表明数据不符合期望，执行失败策略
校验方式：
- [Expected-Actual][期望值-实际值] [Actual-Expected][实际值-期望值]
- [Actual/Expected][实际值/期望值]x100%
- [(Expected-Actual)/Expected][(期望值-实际值)/期望值]x100%
操作符：=、>、>=、<、<=、!=
期望值类型：固定值日均值周均值月均值最近7天均值最近30天均值源表总行数目标表总行数
例子：
- 校验方式为：[Expected-Actual][期望值-实际值] [操作符]：> [阈值]：0 期望值类型：固定值=9。
- 假设实际值为10，操作符为 >, 期望值为9，那么结果 10 -9 > 0 为真，那就意味列为空的行数据已经超过阈值，任务被判定为失败

🐠运行失败

按理说应该成功才对，结果不会小于0的

测试用的spark是3.2版本，不知道报错是不是这个原因，暂时没时间研究了，有知道的欢迎指教
