Etcd: compile clientv3 with newest grpc failed

I use clientv3 in our project, but compile failed after I update grpc.

etcd uses cmd/vendor directory to store external dependencies, which are to be compiled into etcd release binaries. client can be imported without vendoring. For full compatibility, it is recommended to vendor builds using etcd's vendored packages, using tools like godep, as in vendor directories. For more detail, please read Go vendor design.

The etcd's vendored gRPC might be different than yours. Could you check? We use https://github.com/coreos/etcd/blob/master/cmd/Godeps/Godeps.json#L211.

I force using git reset --hard 9ac074585f926c8506b6351bfdc396d2b19b1cb1 for grpc and it works now.
