The require_relative method is not included since it was introduced in Ruby 1.9.2, later than the minimum version (1.8) for which the original code is checked. Also, CGI.escape is used instead of CGI::escape to reflect the changes in the CGI library. I almost needed this for a project on some very old infra. But ended up not needing it and didn't want it to go to waste.
Here we have a Ruby script that checks if kerberos authentication is enabled or disabled. If it's set to true, the script outputs "Kerberos authentication is enabled". And if it's set to false, the script outputs "Kerberos authentication is disabled". Along with that, I added some extra methods in the FileUtils module that allow you to set up various configuration options for a WebHDFS client. For example, you can set the host and port of the NameNode, enable or disable SSL and HTTPFS mode, and so on.
I refactored things so the error classes are directly defined as subclasses of the WebHDFS::Error class instead of using the older syntax of class definitions. Additionally, the Class. new method is used to create new classes, a more concise and modern way of defining classes in Ruby.
