Requesting a reply on below thread. if any one can clear my doubts it would be a great help.
As I am appearing for CCA 175 exam next week. I have few doubts.
I have completed the youtube playlist of CCA 175 and practiced multiple questions.I have used spark 1.6 for solving the problems and I am very comfortable with data frame and spark sql using spark 1.6.
However in last month’s youtube session Durga sir has advised to use Spark 2 in the exam.
- Will there be any changes in the APIs for reading and writing the data using Spark 2 ?
- Can I launce Spark2-Shell and follow the same coding pattern I practiced in Spark 1.6 ?
- Should I use Spark 1.6 and proceed with my certification next week as I have put 2 months effort in learning and practicing ?
