A while back, actually quite some time back in Map Reduce Applications with z2 – Part 1, I promised some more details on how to run deeply integrated map-reduce jobs on Hadoop and HBase with z2.
I finally got around to describing a complete sample that I used for my talk Buildfrei Skalieren für Big Data mit Z2 (slides available following the link) at the Entwicklertag conference in Karlsruhe. It took me a year to finally turn this into a sample from the Wiki…
Anyway. You know Hadoop/HBase? You know how painful it can be to re-use application level services in mapper or reducer tasks? Then you should take a look at the
Sample that combines HBase with full-stack Spring and Hibernate usage
