This should not be necessary once the new balancer API is done. Currently interop clients don't use balancer. With a non-blocking dial, the first failfast RPC will fail because there's no connection available. This is a known bug, and will be fixed by the new balancer APIs. This is a temp fix to make interop tests pass.
gRPC-Go
The Go implementation of gRPC: A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the gRPC Quick Start: Go guide.

$ go get -u google.golang.org/grpc
Prerequisites
This requires Go 1.6 or later.
Constraints
The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the list, you need a discussion with gRPC-Go authors and consultants.
Documentation
