Sounds like either the light fixture or the light switch or the wire from light switch to light fixture has a short in it and this is the problem. Turn off the circuit breaker that powers this circuit. Then disconnect the light fixture, tape over the bare wires that fed the light fixture so the two do not connect each other. Turn on the breaker and turn on the light switch. If breaker pops, we know the switch has a short in it - replace it while the light fixture is still not connected and test it again. If it fails again there is a short in the wire to the light from the light switch and if you cannot see the fault by an examination for loose insulation at both switch and fixture end, you will have to replace wire from switch to light and test again. Of course, turn off breaker to replace and inspect. Test again and if the breaker does not trip with the light fixture lead wires still disconnected and taped, it is time to connect the fixture back into circuit. Turn off breaker and do this. Now turn on light and if breaker trips, the fixture is bad and it needs to be replaced. I know this is a bit of "detective work" but it is what is needed.

Since you ask here it shows that you need the help of a qualified professional electrician to do the work.
