Thanks, Brad, that makes it very clear what I can expect.

Hello, Does anyone know if there are any free re-takes available for this exam if you don't pass it the first time, or is it a "pay-as-you-go" approach? I looked around on the website but couldn't find any information about this. Thanks!

Hi, Sean - Yes, that does help. I took the Developer course and we discussed this. I was surprised to learn (and it's obvious to me now) that book indices are actually inverted indices! Learning to think in Hadoop and M/R will be the first challenge to overcome as I begin my efforts in working in the Big Data arena. Thanks for your help. Kevin

Oh, I didn?t try that. I was looking in the documentation provided on the Express page (tab along the row where the download section is) and perhaps it is documented there but I didn?t read far enough into it. I?ll give it a try later and respond on the forum. Thanks for the quick reply. Kevin

Hello, I have downloaded the .bin file onto my Ubuntu system but there is no way to install it. The installation instructions were of no help, either. It seems there is only one format for all OS types?

Thanks, your answer was fine.

Is a combiner always defined in terms of a reducer or is there another way to code the combiner class? Thanks in advance to all who answer.

I'm looking for clarification on something I've read in Hadoop: The Definitive Guide. It states that map output is local and not in HDFS. But the map task runs on the node where the data resides (usually) and that is HDFS, correct? Or is it the case that the I/O done by the map is standard Java I/O and not something like hadoop fs -put? Thanks in advance to all who answer.

Hello, I am just starting my education in the world of big data, Hadoop, and MapReduce. While I understand the concept of inverted indexes, I'm not sure I understand the purpose. What problem is being solved by creating an inverted index? What valuable information does such an approach provide? Thanks, Kevin
