register := zk.NewRegistrar(client,zk.Service{
	Path: "/services/hello",
	Name: "abc",
	Data: []byte("http://127.0.0.1:8080"),
},logger)

It will be created in zk

[zk: localhost:2181(CONNECTED) 161] ls /services/hello
[_c_c83db041ac654566228b72cbd541bcb5-abc0000000006, abc]

/services/hello/_c_c83db041ac654566228b72cbd541bcb5 is correct
/services/hello/abc is empty node

//will get 0 instance
zk.NewInstancer(client,"/services/hello/abc",logger)
//will get 2 instances, one of them is <nil>
zk.NewInstancer(client,"/services/hello",logger)

In my understanding, CreateProtectedEphemeralSequential function will be created under /services/hello/abc

So is this a bug? Or there's something wrong with my usage?

```golang
register := zk.NewRegistrar(client,zk.Service{
	Path: "/services/hello",
	Name: "abc",
	Data: []byte("http://127.0.0.1:8080"),
},logger)
```

[_c_c83db041ac654566228b72cbd541bcb5-abc0000000006, abc]
```
**/services/hello/_c_c83db041ac654566228b72cbd541bcb5** is correct
**/services/hello/abc** is empty node

```golang
//will get 0 instance
zk.NewInstancer(client,"/services/hello/abc",logger)
//will get 2 instances, one of them is <nil>
zk.NewInstancer(client,"/services/hello",logger)
```
In my understanding, [CreateProtectedEphemeralSequential](https://github.com/go-kit/kit/blob/master/sd/zk/client.go#L241) function will be created under `/services/hello/abc`

So is this a bug? Or there's something wrong with my usage?

I don't have enough knowledge about ZooKeeper to give any opinion here.

I guess it's fine?
