Hey everyone,
I’m trying to impliment httpClient classes for Spark core and I seem to be getting errors that I just don’t know how to fix. These are the errors.

It tells me on line 257 of HttpClient there is a unrefined reference, but I checked and the code seems fine to me. It would be great if someone could help me in the right direction. Here is were I received the HttpClient class code.
Thank you!
