jfuechsl opened a new issue, #4283: URL: https://github.com/apache/arrow-rs/issues/4283
`AmazonS3Builder::from_env` sets the metadata_endpoint with a postfix from the `AWS_CONTAINER_CREDENTIALS_RELATIVE_URI` env var (provided by the ECS environment): https://github.com/apache/arrow-rs/blob/17ca4d51d0490f9c65f5adde144f677dbc8300e7/object_store/src/aws/mod.rs#L610 However, this line uses the static `METADATA_ENDPOINT` which is hard-coded to "http://169.254.169.254" . This is incorrect according to AWS docs; the correct METADATA_ENDPOINT in this case should be "http://169.254.170.2". (see the [docs](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-iam-roles.html)) I'd be happy to submit a PR for this once you confirm this is an issue. -- This is an automated message from the Apache Git Service.
