[GitHub] [druid] gianm opened a new pull request, #13413: ServiceClient: More robust redirect handling.
gianm opened a new pull request, #13413:
URL: https://github.com/apache/druid/pull/13413
Detects self-redirects, redirect loops, long redirect chains, and redirects to unknown servers. Treat all of these cases as an unavailable service, retrying if the retry policy allows it.
Previously, some of these cases would lead to a prompt, unretryable error. This caused clients contacting an Overlord during a leader change to fail with error messages like:
```
org.apache.druid.rpc.RpcException: Service [overlord] redirected too many times
```
Additionally, a slight refactor of callbacks in ServiceClientImpl improves readability of the flow through onSuccess.
