Thank you Durga and Arun Kumar for your videos and exercises. all the learning materials provided by you are so great, more than enough to pass the exam.
I passed 8 out of 9 (2 sqoop, 7 spark-shell), not sure why one of the spark question failed. all questions are easy. do not worry if you know all the concepts in Druga Sir’s videos/exercises and you can finish the mock questions in Arun’s blog in time and accurate, you are good to go.
my tips are (1) better to have a big monitor for the exam. (2) pay attention to the output requirements.question is easy, but if you miss any output requirement, you are finished, so validate your output file(location, file format, file content, compression, record count…) carefully. if you have enough time, you can use both HDFS commands and Spark-shell to check/reverse check your output.
