Sourav, On twitter you asked "why is it opening so many file handles"
Your processor is not. It may well be just fine. However, at startup nifi loads many files into the classloader and it is at the point now where it references more than 1024 objects (files, sockets, etc..) so it is important to set a higher default. I encourage you to go ahead and follow the best practices mentioned in the documentation and I suspect you'll find your custom processor is doing what you expected.
