Hadoop exercises
Hi,
what would you think of these
exercises<http://hadoopinpractice.blogspot.com/2011/01/exercises-for-chapter-1-how-do-they.html>for
the Hadoop intro chapter?
Thank you,
Mark

Again, I agree.
It's not even for lazy ones, it is required! The lazy one was I for not
including this before. That's fixed
now<http://hadoopinpractice.blogspot.com/2011/01/exercises-for-chapter-1-how-do-they.html>
.
Thank you,
Mark

For the even lazier, you could give both the test data and the
expected output data. That way they know for sure if they got it
right. This also promotes a good testing best practice, which is to
assert against and expected set of results.

Thank you, Harsh, for the suggestion. It also gave me an idea to add one
more exercise, "generate test data" - which is helpful in its own right,
since it brings out the idea of Hadoop testing philosophy: think of large
tests.

Providing a data sample after describing it would be good for the yet-lazy.
