java - HiveDriver 类NotFoundException

Question

我创建了一个带有依赖项的 Maven 项目

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-core</artifactId>
    <version>1.2.1</version>
</dependency>

我面临以下异常 private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver";

java.lang.ClassNotFoundException: org.apache.hadoop.hive.jdbc.HiveDriver
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:264)
    at sample.HiveJdbcClient.main(HiveJdbcClient.java:18)

Answer 1

我想你需要这个:

<dependency>
    <groupId>org.apache.hive</groupId>
    <artifactId>hive-jdbc</artifactId>
    <version>2.3.2</version>
</dependency>

根据 HiveServer2 运行的内容更改版本
