After we retry, we found there are two tasks running in the Druid web console. This error occurs occasionally.
- We check the Overlord pod log, it didn't have related exceptions.
- Some blogs say it is because Golang used exists HTTP connection. We set req.Close=true, create a new connection when every request, but it still works.
I would love to get input from you experts.
Let me know if there is anything I can share that might help shed some more light.
