'hadoop' in the above line is a shell script that's present in the
hadoop-common/bin location. If you see that script, you'll notice that
it processes many secondary commands, like 'jar', in this example. And
for each such command, the corresponding class file is referred. For
e.g., jar is mapping to "org.apache.hadoop.util.RunJar"

Could this not be done by using the Configuration object to pass in
additional options ? A little more information about your use-case
