> don't yet understand the need for passing the metadata error around in a Future. And I'm also still wondering if this could be handled at a lower layer so that we don't have to have bespoke code in the request managers to deal with it. The rationale behind this design is that when `ConsumerNetworkThread#processApplicationEvents` executes `checkAndUpdatePositionsEvent`, the T`opicAuthorizationException` doesn’t surface immediately. Instead, it may require several iterations of `runOnce` for the error to become apparent. Without using the future-based approach, it would be impossible to propagate this error from the background thread to the `OffsetsRequestManager`. -- This is an automated message from the Apache Git Service.
