'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" > I am looking for a file in our hadoop code where these are received as args. > > Intention: to control while adding additional user input from command line > arguments for the map reduce framework processing. > Could this not be done by using the Configuration object to pass in additional options ? A little more information about your use-case could help.
