我正在尝试连接Apache Superset和Dremio，两者都部署在Kubernetes集群内。虽然设置与this post中描述的问题非常相似，但我认为与Kubernetes相关的一些细微差别可能会导致问题。

设置：

Apache Superset: Deployed on Kubernetes using the official helm chart (3.0.0).
Dremio: Also deployed on Kubernetes using its respective helm chart (24.1.0).
Python: v3.9.18
sqlachemy-dremio: v3.0.3

使用的连接字符串：

dremio+flight://dremioUser:dremioPwd@<dremio-service>.<namespace>.svc.cluster.local:32010/dremio

**遇到错误：**在Superset中按下“测试连接”按钮时，遇到以下错误：

The above exception was the direct cause of the following exception:

采取的步骤：

1.从Superset pod中检查Dremio服务的可达性。未检测到问题。
1.已验证是否在Superset pod中正确安装了sqllogy-dremio。
1.使用Python脚本测试从Superset pod到Dremio的连接。此连接成功，表明没有明显的网络或服务问题。
但是，通过Superset UI连接仍然会抛出错误。
我已经浏览了上一篇文章的建议，但没有任何运气。鉴于这两个服务都在Kubernetes上，我想知道是否有任何我可能忽略的特定配置。
如果任何人在Kubernetes环境中遇到过类似的问题，或者对潜在的修复方案有深入的了解，我们将非常感谢您的意见。
