Hi, 
  I would like to use the createRemoteEnvironment to run the application
in a cluster and I have some questions. Following the documentation in
[1] It is not clear to me how to use it.

What should be the content of the jar file? All the external libraries
that I use? or need to include the program map/reduce to be distributed
as well? In the last case, why should I redefine all the operations
again in the main source? Shouldn't be included in the jar files? 

Many thanks
Juan
