HTrace didn't get its own GUI until 4.0, and that wasn't really ready until 4.1. There might be some kind of GUI in HBase or Phoenix but I'm not familiar with that. 3.1 was basically a straight port of the old github code into an apache namespace, plus a lot of license and other cleanups. It really is a very old release now.
