HR investigation against me closed. What would you do?

I had a hr complaint made against me. Basically I was said to be creating a hostile work environment. Shut people down, didn't take feedback, and was said to be negative. People supposedly didn't want to work with me because why wanted to avoid conflict.

My company's HR investigator asked everyone of my coworkers and everyone in my section. Total was 20 people that gave statements about our work environment.

Case closed. Turned out none of what was brought about me could be validated by others. What they did find was that the person that made the complaint was found to be making things hostile, not taking feedback, and people avoided when possible.

I'm not sure what happens next. Anyone been on this before? Advice? Does the person get in trouble for making the complaint and actually being a problem?
