It is affectionately said that what Oracle is to Relational Database, Cloudera is to Hadoop. Most of the Hadoop aspirants, at the beginning of their Hadoop development learning curve, fiddle with the setting up of CDH, some able to do it smoothly (Cloudera has put up an incredibly exhaustive installation guide), some requires to really sweat it out (few finer details and prerequisites are either missing or not enough emphasized upon) and very few actually gives it up losing their way in the verbose and cover-all-cases installation guide(multiple way of set up and different set of instructions for different linux OS; sometimes too much of variations for impatient starters). So there is a target audience for one more set up document which is leaner, meaner and streamlined with only one (the most preferred) variation. Try it at home!!

My learning phase with Hadoop is still continuing. During this phase what I found is a great lack of a comprehensive POC which covers at least a few prominent Hadoop technologies. My POC can fill up that void. After having set up CDH4.7 in my laptop, I completed implementation of this POC touching HDFS API, MapReduce, JSON and AVRO SerDe, HBase.
