Agree that Impala would fit well on this list. They didn't have any training on it, presumably because it's a Cloudera-led technology, but my understanding is it's very popular. Not sure that it truly replaces Hive/Tez though. I think they each excel at certain types of workloads.

I think the term "Hadoop" is becoming almost meaningless. It seems to now be more of a pointer referencing a basket of distributed processing technologies that run on YARN/HDFS. Agree completely with having multiple technologies to solve every problem, that's one of the most confusing parts to learn.

My own perspective is that there are lots of businesses that haven't yet needed the capabilities provided by a platform like Hadoop, but they likely will in the future. So the market may be saturated based on current needs but that market will continue to expand. Whether it's Hadoop (YARN/HDFS/etc.) that wins that market share or some other stack like Spark/Mesos remains to be seen.

I don't see much value in continuing to debate this. You're entitled to your opinion and I respect that, but I do not share your viewpoint.

Since you linked to the honor code, can you point to anything in these blog posts that qualifies - in the context of completing the class - as "solutions to homework, quizzes, exams, projects, and other assignments"? Could anything I provided be directly used to "cheat" and finish the class without doing the work?

And just as a practical matter, there are dozens of github repos with literal (as in copy, paste, submit, done) solutions to these problems already available.

You're certainly free to disagree, but I do not view this as violating either the spirit or the intent of the honor code. This content has been out for years and is not in any way novel or unique. It's simply another vector through which the material can be learned, possibly opening it up to an even wider audience. Which is, I believe, what Andrew's goal was all along.

None of the material in these posts could be used directly to complete assignments for the class. I suppose someone could attempt to "back-port" some of the Python code to Octave, but if you're going to that much trouble it's probably easier to just solve it in Octave in the first place.
