You require hadoop-hdfs dependency for HDFS FS to get initialized.
Your issue lies in how you're running the application, not your code.
If you use Maven, include "hadoop-client" dependency to get all the
required dependency for a hadoop client program. Otherwise, run your
program with "hadoop jar"
