Hello again Shreya,
That signature (for configure) looks right and I think it indeed gets
called. Unsure about your map call issue as I do not see that signature.
Perhaps what you need to resolve this issue by yourself is to make use of
the @Override method annotations in your code. That helps a lot when dealing
with frameworks, such as Hadoop.
