Hadoop online training at DataFlair was excellent. I am from an ETL background having not much knowledge of Java programming, This was one of the carefully crafted course which emphasised on mapreduce programming and HDFS. Reinforcement of concepts through repetition was the best part. The course content and structure was excellent and more than enough to make student start in the area of hadoop. The trainer was able to solve my queries. Doing assignments and weekly projects, researching through topics, Doing projects after course, practical sessions and code walkthroughs were my favourite part. Participating in quizzes and getting apt feedback from trainer helped me in increasing my confidence.
