hadoop - 错误配置单元(使用 Derby): Source tables cannot be empty

Question

我刚开始使用 Hive，遇到一个错误需要您的帮助。在等待一段时间后，当我尝试创建一个新数据库时，它发生了:

 hive> CREATE DATABASE Test;

(编辑:我对“SHOW TABLES”有同样的看法)

我明白了:

我或多或少遵循了这方面的步骤:https://cwiki.apache.org/confluence/display/Hive/HiveDerbyServerMode .我错过了什么？谢谢!

Answer 1

我终于找到了解决方案:

我必须运行 sql 脚本:$HIVE_HOME/scripts/metastore/upgrade/derby/hive-shema-x.x.x.derby.sql。为此，我使用了ij。
