Happy that Im a certified Hadoop developer!
Just got certified yesterday after a failiure 2 weeks before.. I misjudged the test at first and not much prepared. The questions are more diversedfrom Hadoop, DFS concepts, mapreduce,java, little administration , pig, hive, flume etc.. but mostly on mapreduce and practical implementations.
The test is certainly testing on your practical knowledge onHadoop, one who has good hands-on experience and very good on the concepts can pass...
