beeline -help我尝试使用另一种连接方式，即，beeline -n username -p password -u jdbc:hive2://hs2.local:10012并得到了这个：

如果您在 docker 中运行 hive 服务器并尝试在 docker 中连接，则不应将主机名用作localhost. 使用 hive 服务器的容器名称作为主机名。

beeline -u jdbc:hive2://<container_name>:10000

经过同事（https://github.com/rbonela）的研究和帮助，发现问题出在目录中的权限被拒绝：/var/lib/postgresql/data

因此，解决方案是杀死所有容器，编辑 docker-compose.yml 文件，在 hive-metastore-postgresql 配置部分，将目录更改为/var/lib/postgresql/data您喜欢的另一个目录。

再次测试一下。这对我有用。
