can't use etcd by go mod?

[smallnest]

Go version: 1.13

If I download etcd by go mod, it shows an error:

build github.com/coreos/etcd: cannot load google.golang.org/grpc/resolver/dns: module google.golang.org/grpc@latest (v1.25.0) found, but does not contain package google.golang.org/grpc/resolver/dns

The package google.golang.org/grpc/resolver/dns has becomed "internal" and etcd has use its own the package in vendor, but if I use go module or imported etcd in my go.mod, an error was thrown and the operation failed.

I ran into this same build issue today, it's due to the latest release of grpc moving that package. The build error can be worked around if the grpc 1.24.0 version is used.

This ticket could probably use a better name, but the corresponding issue on the grpc side is here: grpc/grpc-go#3157

The long term fix is that etcd probably shouldn't be using this package directly, the public interface is resolver.Get("dns")

FYI, The moved packages will be added back in grpc/grpc-go#3162. Those packages will be thin wrappers of the public APIs (e.g. resolver.Get("dns")). A minor release will be made for this change.

If it's necessary to get a DNS resolver builder. It's unclear why etcd is importing the DNS package, however, as this is unexpected - can anyone explain?

I think this is fixed via #11823.

I am closing this under that assumption. Please correct me if I am wrong.
