无法打开与 HS2 服务器的连接
Could not open connection to the HS2 server
我正在尝试使用命令 beeline -u jdbc:hive2://localhost:10000 连接到我的 docker 容器中的配置单元服务器，但出现错误：

所以我知道这是怎么回事以及如何解决这个问题。我错过了什么？
如果您是 运行 docker 中的配置单元服务器并尝试在 docker 中进行连接，那么您不应将主机名用作 localhost。使用配置单元服务器的容器名称作为主机名。
beeline -u jdbc:hive2://<container_name>:10000
经过研究和同事（https://github.com/rbonela）的帮助，发现问题出在目录中的权限被拒绝：/var/lib/postgresql/data
所以，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 /var/lib/postgresql/data 更改为另一个你喜欢。
再次测试。这对我有用。
