how to fix it please help

Hi, it is a warning, so by definition you can't fix it because there's nothing broken. There is only a performance penalty to pay for this warning. Second it's a hadoop issue so you are more likely to find the answer on hadoop-related support forums. I would search for <your OS here> hadoop native libraries. I develop on a mac and I always see this warning and I just ignore it.
