Hello Sophie, If you're using the HDFS lib like you said (i.e. obtaining an instance of FileSystem and using its methods), then I expect your code will "just work" with no code changes required when you start running against a secure cluster. The work of switching to a secured deployment with Kerberos is mostly a matter of configuration:
http://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-common/SecureMode.html This configuration is external to application code.
