[GitHub] [arrow-rs] jfuechsl commented on issue #4301: [Question - object_store] AWS credentials provider

   Understood, thanks for the elaboration.
   
   Unfortunately, I realised that the ECS credentials fix does not work. The reason is that the metadata endpoint is still being used in the context of the EC2 credentials provider `InstanceCredentialProvider`, which further appends a path to the endpoint https://github.com/apache/arrow-rs/blob/ea008922445d84d957cf3f89df793187c22d82d8/object_store/src/aws/credential.rs#L429
   
   A proper fix would need to adapt the credentials resolution logic in `AmazonS3Builder::build` by including a ECS specific provider (thus mirroring the official resolution chain in the AWS SDKs).
