First of all big thanks to Durga Sir and Arun Sir.
My exam pattern was also same as others (2 sqoop and 7 spark questions).
Exam was pretty easy or I would say became easy because of Itversity and Arun sir.

If you are following video series for concepts and solved all questions :
From Itversity –
i) spark exercises (http://discuss.itversity.com/c/certifications/spark-exercises) and
ii) workshop exercises (http://discuss.itversity.com/c/big-data/workshop-exercises)
From Arun’s blog – (http://arun-teaches-u-tech.blogspot.com/p/certification-preparation-plan.html)
you are good to attempt exam.
I am listing few points as per my experience:
- time management – very important.
- screen resolution is really small so be prepared. Make sure your keypad/mouse works perfectly fine.
- I felt sqoop questions were somewhat trickier then spark questions.
- Spark questions were really easy.
As Durga sir explained in videos about spark question pattern -->
i) read data in some file format or from hive. For text file practice with different kinds of delimiters, like comma(’,’) or tab (’\t’) or pipe (’|’)
ii) select few needed fields, perform simple transformations. Transformations was not that complicated, so you can keep that in mind. for example, groupBy, sum, count, join, etc
iii) sort the data as per specification, means with some specified fields in ascending or descending order. (I found, in one question where they have not specified directly about ascending or descending but they have explained the requirement and based on that we need to interpret the desired sorting pattern).
iv) save the data in asked file format and apply compression technique if asked.
- verification is really important. I would suggest to cross check your answers right away instead of verifying at the end. you might not get time at the end of exam.
Feel free to ask any questions.
@itversity, please correct (as per cloudera guidelines) if i unknowingly listed some information.
