Hi,
I want to take up new CCA175 certification sometime in January. Can someone provide details on Study materials i can refer to prepare for this exam. Since this certification is pretty new, I don't see much references on google.

The CCA-175 exam is a hands-on, scenario-driven test. You will be asked to solve problems. The grading will be based on the solutions that you provide. We do not evaluate the tools or the code that you used to solve the problems.
Can you use Pig? Absolutely. It may be possible to solve every one of the problems on the exam using just Pig if you are an expert. It may not be practical, however. There may be better tools for interacting with the Hive metastore to do DDL, such as Impala, Hive, HUE, HCatalog, etc. Similarly, the coding questions will give you Spark templates to add code to. You may not have enough time in the exam to code everything from scratch in Pig. Pig is not listed in the Required Skills, because there will not be a specific question where you are required to use Pig on the exam.
The Required Skills section contains this line:
There is no contradiction. This is a "problem solving exam" as opposed to a "tools exam". You will need to be able to use Hadoop tools to generate solutions, but the tool that you use is up to you.

The site for the exam is here: http://www.cloudera.com/content/www/en-us/training/certification/cca-spark.html
It is a hand-on exam, so there is not a book that is going to give you all of the answers. The course Cloudera Developer Training covers the topics as well as giving you hands-on exercises to practice.

where we can find, study material? LIke what needs to studied by us? and what kind of questions etc?

That sounds like we can not be confident unless we sign up for Cloudera's training. I welcome the performance based skill testing method but Cloudera should not force us to signup for their training by not spill the beans.
I also need to know if we require to code in Scala AND pyhon for all the problems.

Thanks for reply Brad, good to hear from Cloudera folks.
Like you pointed out importing data from MySQL sounded really simple to me and thats what made me wonded "what else is in there ?"
I'm a self learner, relying on Coursera(for Scala, Python), Edx(Spark) and Cloudera VM. By chance will there be some sample excercie on Clouder VM in future release, it will help developer community a lot since all of us don't get an opportunity to work on all of the exam objectives at work/school.
And about my other question, do I need to write program in Scala and Python ? I'm good @Python and just getting started with Scala.

when we answer a question in exam and compile(submit) it, does it tell you whether it was correct or not (I mean for individual questions not for entire exam)??

Thanks for clarifying on these questions. Do we need to know both Scala and Python? Is Scala alone not enough for coding?

From the community FAQ on certification.
The answer is yes, there are questions using both languages.
However, please remember that the goal of the exam is to test your Spark knowledge, not your Scala and Python knowledge. The development questions typically provide you some code and ask you to fill in TO-DO sections. So the key is to understand the Spark API. You must have some knowledge of programming, as you will need to be able to read the existing code and understand how to store and retrieve the results you get back from calling the API, but the focus will be on you adding the Spark calls.

Bumping this slightly to get more up to date answers on study materials. There's a book on amazon for CCA 175 which looks decent but seems to be a cheat sheet more than anything else.
Other certifications, e.g. SAS advanced cert, do offer a study guide too. It's a shame that Cloudera don't do that.

Its good that the "Required Skills" section is pretty specific but there is some contradiction.
Under the "Exam Question Format" it mentions impala as copy pasted below
"In some cases, a tool such as Impala or Hive may be used. "
but "required skills" section make no mention of impala.
Similarly, "required skills" section dont mentio pig at all. Does it mean pig will not be asked in the exam? however, pig is included in the list of resources available on exam cluster.
The tools mentioned in the "required skills" section are:
MYSQL
HDFS
Sqoop
Flume
Hadoop fs
spark
hive meta store
avro
json files
and you can see the list do not include pig or impala.

Hi Brad,
As for spark test part, can I choose either Python or Scala for exam? Or does I have to learn both Python and Scala to pass the exam?
Thanks

Hi Brad,
I took the Developer Training for Spark and Hadoop last month. And I am planning for CCA175. But when I look at the skillset here -http://www.cloudera.com/training/certification/cca-spark.html , I see the Data Analysis part was not covered in the course, and instead Kafka and Flume has been covered in the course.
Can you please confirm if the CCA175 will include the updated content (wihth Kafka, Flume) or it still will include the Hive, Impala? And how long will the CCA175 include Data Analysis part? PLease advice as I am planning for certification soon.
Thanks
Priti

Hi Brad,
I am planning to give my cloudera CCA 175 exam soon. I found that there is very little mentioned about Hive (topics like paritioned/bucket tables) or Avro (topics like Schema evolution etc) in the objectives on this site https://www.cloudera.com/more/training/certification/cca-spark.html.
Does this mean there will be no question on the advance topics in Hive or Avro in the exam ?
Created 10-02-2017 05:28 AM
I looked over the CCA175 page and while there is little mention of Hive or Avro one particular section stands out.
Each CCA question requires you to solve a particular scenario. In some cases, a tool such as Impala or Hive may be used. In other cases, coding is required. In order to speed up development time of Spark questions, a template is often provided that contains a skeleton of the solution, asking the candidate to fill in the missing lines with functional code. This template is written in either Scala or Python.
You are not required to use the template and may solve the scenario using a language you prefer. Be aware, however, that coding every problem from scratch may take more time than is allocated for the exam.
Perhaps you are looking at the exam as individual questions rather than tasks to complete. I would look over the required skills portion of that page and think about how you would accomplish each task. If Hive and Avro would be involved in your process to comlete a task, then prepare accordingly.
I hope this helps.

You mark this as solved ... But, that is not correct. It is not solved...
We understand Cloudera Training provides all the necessary information for this exam...
Any certification should provide study materials...
Especially when the training is not mandatory and also for those who don't want to take an expensive training (not all will be able to take it) and may want to use a study material and do the hands-on on their own to get this certification...
It will be great If Cloudera could provide a study material (paid one) for this course (I am not talking about a free study material)...
Thanks.
