There should be 404 page for unrecognized paths

[mcapuccini]

As it is now the proxy returns the Spark master homepage for unrecognized path. E.g.: localhost:9999/yadayada returns the Spark master home page. Why not to return 404 in that case? If you think it is a good idea I can send you a PR as soon as I have some time.

Interesting!

It looks like Spark is at fault here:

$ curl -vs http://localhost:8080/aaaaaaaa
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET /aaaaaaaa HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.53.1
> Accept: */*
>
< HTTP/1.1 200 OK
...

I'm not sure we can fix this in the proxy without the solution being a hack. Ideas?

I see. It's mostly a Spark UI problem then I'd say. If you don't mind we could leave this open for a while, if I have some spare time I could try to find a solution.

Sounds good. Thanks for your contribution.
