Hi I am.ankush thakur I have done hadoop course from. Mindscript technology. See guys you have to do it in tour way because no ine can help you in getting your job. First you have to mind set that you have to prepare by your self for learning. hadoop trainer was very good in knowledge if want to join hadoop please go for Hardeep Saluja' Classes. He is very talented guy wokring in. zs talented guy if he teaches you you never gonna be forget hadoop.the way he is teaching very fab. Very few person have this type of talent. So go for hadoop. I personally recommded Hadoop but learn from Hardeep.
