Cleared CCA 175 on 17th April 2019

#1

Hi,

I cleared my CCA 175 exam yesterday (17th April). I got 8 out of 9.

Firstly, I would like to thank Mr.Durga and his team for helping out aspirants like me with the content to be able to take up this exam with ease. Kudos to him!.

The exam problems were straightforward although some questions need to be read more than once to interpret right, as we need to just apply our mind and knowledge at that very moment. The exam time is quite tight to be able to finish all the problems.

My suggestion would be to practice well before giving it a try. Also, please do take backup of data for the sqoop and hive related problems, that would really help in accidentally losing it. I did the backup as recommended and it helped in my hive question. Also, please check the data structure, sample output and the delimiter before proceeding with the solution.

Good luck to all the aspirants!

Thanks again to Mr.Durga and this active discussion forum,

Malli

Congrats, Malli !
May I ask how many questions did you get on Spark streaming (flume/kafka etc)?
In the Spark-SQL do they ask specifically to implement using Core API or using Data Frames/SQL ?

Thanks

Thanks Soumyajit_De.

I did not get any questions on Spark Streaming, flume or kafka.
It is up to you to use Core API or DF or spark sql based on the problem statement. There was no mention of which one to use to solve the problem.

I got 2 sqoop, 1 hive and 6 spark questions.

Thank you hhena.

I did use scala doing spark problems in spark-shell.
I took only Mr. Durga sir course in youtube and referred some books for further information.

Thanks Malli for the prompt response.

Sorry 1 more question - when you say taking the back up of the data, did you mean copy the data from HDFS into some local folder?

I hope we will get enough time for this kind of extra works.

Thanks

Hi Malli,

Congrats!

I attempted last week, but unfortunately, I was not able to clear it.

Got a sqoop question to import columns from MySQL but there were no column names specified it was more of vague columns mentioned, so missed that
Did you face any such question?

T&R,
Rihan

Yes Soumyajit, I did mention about taking the backup of data from HDFS to local file system.
I would suggest to do this backup only for sqoop and hive related questions where data conversion type of problems are being asked.

Time is quite tight to finish all the problems.

Thanks Rihan.

Sorry to know about your attempt.

I used sqoop eval command to make sure of the table schema and the number of rows before I attempted any sqoop or hive related questions. That really helped me to make sure of the column names in the problem statement with the table schema.

Also, with the spark questions too, I did verify the data structure from a file in the source folder, to make sure of the data layout and its delimiter.

Good luck to you!

Hhena, I referred online resources for Scala but for this exam whatever knowledge we gained from the content by Mr.Durga is more than enough.

I gave more emphasis on Spark, So I read this book “Learning Spark” by Matei Zaharia…
