The latter is because running a Hadoop program requires Hadoop
dependencies and configs to be available in its runtime classpath.
This can be achieved by either creating a fat jar assembly, containing
config files and all required dependency jars; or you can run it as:
java -cp yourjar.jar:`hadoop classpath` YourMainClass <args> such that
the classpath is automatically setup for you.
