Is there returnValue underlying one atomic operation?

[ghost]

I see one API in 1.2

public void set(String key, String value, Integer ttl, Boolean prevExist) throws EtcdClientException

But it is not with returnValue. I except that some clients concurrently access the proxy under that only one can get the lock ( set key-value is OK).

@fjjiaboming Ok, I will look into.

So now I get key and judge the value after having setted key , that I can regard as one atomic operation judge.

@fjjiaboming So if you have better solution you may open a PR.

OK. I need some time to know the ETCD.
