推荐答案

您是否正在使用Java9?Java 9 Uses不再使用java.net.URLClassLoader.根据: http://openjdk.java.net/projects/jigsaw/talks/prepare-for-jdk9-j1-2015.pdf

Are you using Java9? Java 9 Uses no longer uses java.net.URLClassLoader. According to : http://openjdk.java.net/projects/jigsaw/talks/prepare-for-jdk9-j1-2015.pdf

但是，我能够通过将Hive指向JDK8来解决此问题.

However, I was able to solve the issue by pointing Hive to JDK8.
