what happens if you violate parole by not reporting and stay in street past your discharge date? when you are caught and go to your hearing do they?

You cannot run and hide from your parole and have it discharge on its own while you are on the run.  Why anyone believes this could be true is incredible to me. Your discharge date is meaningless once you go on the run, and a motion to revoke it filed. You will NEVER finish parole - it is frozen once the motion to revoke parole is filed, and no matter how long beyond your original discharge date you run, you will NEVER discharge from parole.
