Hadoop MapReduce Poster
Hi, I'm in the process of putting together a 'Hadoop MapReduce Poster' so my students can better understand the various steps of a MapReduce job as ran by Hadoop. I intend to release the Poster under a CC-BY-NC-ND license. I'd be grateful if people could review the current draf (3) of the poster. It is available as a 200 dpi PNG here: http://www.flickr.com/photos/herberts/6298203371 Any comment welcome. Mathias.

Hi Mathias, Keep me posted as well. I am fashioning a course for Spring 2012 on Distributed Computing using MapReduce, a graduate-level course at The Cooper Union (cooper.edu) Great draft!

Re: Hadoop MapReduce Poster
Hi Mathias, I made a M/R poster too, a long time ago (when I was first introduced to Hadoop). Feel free to use it as inspiration. http://static.kalooga.com/mapreduce.png Cheers, Mathijs On Oct 31, 2011, at 14:20 , Rob Marano wrote: > Hi Mathias, > > Keep me posted as well.

Most of it is probably beneath the radar, but if you want the details of how the sort actually works in MapReduce, I'd suggest going through Chris Douglas' presentation on it. http://www.slideshare.net/hadoopusergroup/ordered-record-collection?from=ss_embed At the very least, you want to show the serialization before the sort in the Mapper and deserialization in the Reducer, which gives you a good platform to talk about why you need to define RawComparators for your key types if you want reasonable performance out of the sort. -- Owen
Re: Hadoop MapReduce Poster
Hi Mathias, I wrote a small introduction or a quick ramp up for starting out with hadoop while learning it at my institute. http://functionalprograming.files.wordpress.com/2011/07/hadoop-2.pdf thanks -P On Mon, Oct 31, 2011 at 6:44 PM, Mathias Herberts < mathias.herbe...@gmail.com> wrote: > Hi, > > I'm in the process of putting together a 'Hadoop MapReduce Poster' so > my students can better understand the various steps of a MapReduce job > as ran by Hadoop. > > I intend to release the Poster under a CC-BY-NC-ND license. > > I'd be grateful if people could review the current draf (3) of the poster. > > It is available as a 200 dpi PNG here: > > http://www.flickr.com/photos/herberts/6298203371 > > Any comment welcome. > > Mathias. >
Re: Hadoop MapReduce Poster
That's a great tutorial. I like the conciseness of it.
