   @ayushtkn Can you help review this pr? I think an upgrade is still necessary.  For the deprecated method, I also made a replacement.

> commons-csv 1.0 is a very old jar, mvnrepository shows this jar as the 2014 version, I have compiled and tested locally, I think this jar can be upgraded to commons-csv 1.9 version.
