Hadoop 2.0 a step forward, but still a just framework for programmers

Back in the 1800s John Godfrey Saxe wrote a famous poem about six blind men trying to discover what an elephant is by touching a part and describing it. Saxe observes that, "each was partly in the right, and all were in the wrong." Fast forward to today and we have a similar situation with Hadoop. Opinions about Hadoop are as varied - and sometimes as incorrect – as they were in the poem.
