I have a program based on wordcount.java
and I have files that are smaller than 64mb files (so i believe each
file is one task )
do does wordcount get the lines in order? or are they random? can i have
hadoop return them in reverse order?

It sounds to me like you're talking about hadoop streaming (correct me
if I'm wrong there). In that case, there's really no "order" to the
lines being doled out as I understand it. Any given line could be
handed to any given mapper task running on any given node.
I may be wrong, of course, someone closer to the project could give
you the right answer in that case.

is there a way to have hadoop hand over the lines of a file backwards to my

as in give the last line first.
