Java 9是否支持hive? [英] Is hive supported for Java 9?

问题描述

每当我尝试加载配置单元外壳时，都会显示此错误:

Whenever I try to load hive shell, it shows this error:

Exception in thread "main" java.lang.ClassCastException: java.base/jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to java.base/java.net.URLClassLoader
    at org.apache.hadoop.hive.ql.session.SessionState.<init>(SessionState.java:394)
