If I understand what you are asking you can use the -cacheArchive with
the path to the jar to including the jar file in the classpath of your
streaming job.

Hi all,
I have an application that i use to run with the "hadoop jar" command.
I have now written an optimized version of the mapper in C.
I have run this using the streaming library and everything looks ok
(using num.reducers=0).
Now i want to use this mapper together with the combiner and reducer
from my old .jar file.
How do i do this? How can i distribute the jar and run the reducer and
combiner from it?
While also running the c program as the mapper in streaming mode.
cheers,
Christian
