All good. Trainer was good in explaining. But one improvement can be allow more lab part. If you say theory for days and at each day one assignment but never validated nor given time to do nor ask questions on assignment. And update course content as well. My trainer after explaining each topic, he used to say this topic may not exist in next version of Hadoop. Like Impala, PIG etc.
