When using library only with udp, still need to provide address in http format

[abadyan-vonage]

If I don't provide a URL with an "http://" prefix, I get a NullReferenceException.
This is not relevant for udp.
Using version 2.5.
The problem is in InfluxDBImpl:
return InetAddress.getByName(HttpUrl.parse(url).host());

You are right, do you have an idea howto instantiate the InfluxDBImpl with the Factory to be safe for both cases ? If yes, please write a PR.

If InfluxDbImpl is initiated with only UDP hostname, then we can't use .query(), `.ping()' or any HTTP functions. The current design mixes both HTTP and UDP hostname in the URL.

I would suggest separating the UDP from HTTP, and we have HttpInfluxDB and UdpInfuxDB, each one with different methods, e.g. .query() in HTTP and .write(udp) in UDP implementation. Both extends InfluxDB interface, which has methods for writing values.

Obviously, this is a breaking change.
