FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

我试图安装配置单元，但它提供了SemanticException。有人可以帮忙吗？

Answer 1

您是否已启动元存储库？您的metastore必须已启动并正在运行，然后才能在配置单元上运行查询。

运行以下命令来创建元数据库

schematool -dbType derby -initSchema

然后启动Metastore

hive --service metastore＆

Answer 2

我遇到了同样的错误，这仅仅是因为有两个SLF4j正在运行，但是java仅使用了一个强制性依赖项，因此您只需要删除该文件。我从蜂巢中删除了它，它才起作用。

您要做的就是删除此文件

log4j-slf4j-impl-2.6.2.jar！

来自

/home/user1/apache-hive-2.3.2-bin/lib /

你很好。

＆＃34;用derby配置hive＆＃34;
