BigTable: row.commit throwing _Rendezvous exception instead of ServiceUnavailable #4656
Description
We are using retry.py and creating a retry exception predicate as follows:
predicate=retry.if_exception_type(exceptions.ServiceUnavailable)However, since we are only getting _Rendezvous exceptions with StatusCode.UNAVAILABLE (see below stack trace), we had to change this to:
predicate=retry.if_exception_type(exceptions.GrpcRendezvous)I see a different issue in cloud datastore for mapping gRPC codes to service level exceptions:
Will this also be done for cloud bigtable?
