Team,
Below (and above) is a link to a book am enjoying browsing lately by top BigData IBMers (Its free download) that i thought would be of value to many of you. It is very IBM centric however it provides great insights into Big Data & provides some detail Hadoop primer to get one started. Enjoy!!
