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

The syntax would be like this:

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

You review the docs for more information.

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

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

If you are new to Hadoop, try using one of the IDE plugins. This will help you get started quickly.

FYI ..... Hadoop on Windows is not recommended for Production.
