Absolutely confident about Hadoop, which i can further reinforce by rerunning through the class recordings and text reading. You presented the topics in such simplistic manner to grasp smoothly. Trainer has amazing energy and enthusiasm. Ensured every single query of the team was handled. At the same time, controlled the flow of class well enough without letting stream of questions derailing the sessions. Examples/scenarios used both as part of planned sessions and adhoc ones in response to queries were very apt and easy to grasp.
