kontrol: ERROR 100: Key not found

I got a problem:
[kontrol] CRITICAL Could not create KitesPrefix "/kites": client: etcd cluster is unavailable or misconfigured; error #0: unsupported protocol scheme ""

etcd version: 3.2.9
I started etcd with default config
kontrol -initial
kontrol -ip=127.0.0.1 -port=6000

Could you please test if it works after applying the following patch:

@rjeczalik
I found etcd.go and changed,
go install github.com/koding/kite/kontrol/kontrol
kontrol -ip=127.0.0.1 -port=6000
there is another problem:
[kontrol] CRITICAL Could not create KitesPrefix "/kites": client: etcd cluster is unavailable or misconfigured; error #0: dial tcp 127.0.0.1:4001: getsockopt: connection refused

dial tcp 127.0.0.1:4001: getsockopt: connection refused

It basically means your etcd agent is not running.

Would you mind sending a PR with the patch above?

I have no PR
I started etcd with default config

@xuanjiang1985 Looks like default hostport value changed for etcd, use -machines flag to point at your etcd, .e.g:

$ kontrol -machines http://localhost:2379

@xuanjiang1985 Could you try master, which should have this issue fixed? If there's anything more, please reopen this issue with the details.

[zhougg]
