I took the Big data and Spark Developer live classes of Simplilearn. The trainer Maria is very good. She explains the concepts very well. She ensured that each and every participant is able to complete the lab sessions. Each and every query was resolved. The content material of Simplilearn is also very good. The lab exercises after each session and quizes helps you to learn things and practise them.
