看了很多的解答，说是版本一致性的问题，那要跟什么保持一致性呢？ 先让spark-hive跟spark-core保持一致。

org.apache.spark spark-core_2.12 2.4.7 
    <!-- https://mvnrepository.com/artifact/org.apache.spark/spark-sql -->
    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-sql_2.12</artifactId>
        <version>2.4.7</version>
    </dependency>

都弄成一样的了，好像不起作用啊。
