* Reject retried RecvTensor requests.Gravatar Jeremy Lau2018-01-22
Retried RecvTensorRequests are problematic because a RecvTensor with no corresponding sender will wait forever, and the tensor may have been delivered to a previous retry. This change adds a unique request_id to each RecvTensor request, and we check these request_ids against a set of recent request_ids. If a request_id is in the recent set, we reject the RecvTensor request. PiperOrigin-RevId: 182863245
