Besides used for making copies of the input, copy stage is also helpful for achieving

1) dropping columns between stages
2) to change column names
3) if the scenario is to end the job flow directly from an active stage where you donot want to write the output to a file, then copy stage can be added after that active stage without connecting any output link to the copy stage.
