Looks like we're just changing the TimeoutException handling on this codepath, but wouldn't we want to change this across the board, i.e. whenever we generate TimeoutException we actually add the last retriable error (unless it's a true timeout and we simply didn't get a reply)? 2. Rather than do this error state tunnelling across multiple levels, wouldn't it be simpler to just add the root cause whenever we decide to initially throw TimeoutException (i.e. when we get a retriable error but throw TimeoutException instead)? Also I'm not sure if we get an error in the metadata request if the topic is just missing -- looks the metadata requests would be successful, just not contain the topic. -- This is an automated message from the Apache Git Service.
