I determine this default by test case, sorry :(
In fact I want to use `noDefaultValue()` here, but I find this method can
be used for `String` only, and there's no `getInteger(ConfigOption<Integer>
option, int overrideDefault)` in `Configuration`.
I think it may be better to add `public ConfigOption<T> noDefaultValue()`
in `ConfigOptions` and add `public int getString(ConfigOption<Integer>
configOption, int overrideDefault)` in `Configuration` . What do you think? THX
:)
