Anything you can do in normal Java code, you can do inside a Storm bolt. Check out any Java HTTP client (OkHttp, Apache HTTP Client, JerseyClient, URLConnection etc.) and use it to fetch the data you need.
If your REST call takes a long time, it might be worth doing so asynchronously and emitting the results downstream when the thread returns. Just make sure that you're synchronizing your OutputCollector when emitting from a multithreaded context. Hope that helps.
