我在用mariadb教程学习apachehadoopoozie时出错了。我是这样运行的：

ooziedb.sh create -sqlfile ooziedb_init_schema.sql -run

但我知道了：

ai@spkm:~/oozie$ ooziedb.sh create -sqlfile ooziedb_init_schema.sql -run

**附加hadoop版本3.2.2 spark版本3.0.2 oozie版本5.2.1 maven 3.6.3 java openjdk 1.8

我在google上搜索这个问题，但是没有任何可用的解决方案。
我不知道为什么它一直不起作用。
为什么oozie需要一个“presistence.xml”文件来运行sql？为什么我的代码不起作用？
