How to readjust landscape's UV?
You can try the "Retopologize" Feature under the Sculpt "tool" dropdown menu. If that doesn't work, you'll need to try to use the smooth tool to smoothing it out a little bit. Typically when developers make "cliffs" in their games, they usually cover up the sides of their landscape with static meshes because of this problem. The Vertex count for landscapes is uniform and depending on the settings for your landscape, usually kind of low. This saves performance. If you're trying to create a cliff though, you'll need to hide the sides of your landscape with static meshes. Otherwise, smooth the edges a bit to try and fix this as much as possible.
