Is your program written in Java? If so, you need to compile your program and pack the compiled files into a Jar file. Then run the program with the hadoop command:

${hadoop_home}/bin/hadoop jar ${your_program_jar_file} ${main_class_of_jar}

You can run Hadoop commands from anywhere on the terminal / command line, but only if the $path variable is set.

The syntax will be like this:

 hadoop fs -<command> or hdfs fs -<command>

You will review the documents for more information.
