This library access information at /v2/_etcd which is no longer made available, and so does not work with the latest versions on etcd. This functionality, which tries to automatically select a different host when there is a problem, doesn't seem to work for me anyway, and I think it is rather against the etcd API as documented. I would suggest to take this out, or make it optional, or at least to update it so that it is compatible with the latest versions of the etcd server.
