CCA 175 Revised Syllabus

ashishdiwan03 — Sat, 27 May 2017 12:06:38 GMT

Hi,

I am CCA Spark and Hadoop Certification aspirant.As per the revised syllabus for CCA 175 do we need to prepare Spark with Scala as well as Python or Spark with Scala is enough for the Certification?

Previous Syllabus mandate Spark with Scala and python but new Syllabus does not provide clarity on the same.

@ashishdiwan03

Earlier they used to provide a code template in either scala/python, so you should know both to fill the missing code based on the template that you have received.

But I came to know from one of the community that with revised syllabus, there won't be any template, so you can write your code from scratch. So you can choose either scala/python.

So the answer for your question is Spark with Scala is enough for the Certification

Hi saranvisa,

I have some queries..it would be very helpful if you can help me with its resolution.

1. Do we need to create jar file for execution of scala program?

2. if yes, could you please help me with the steps of coding during cert exam with a sample problem and steps of execution from begiing of writing code to execution.

Thanks in advance !!!

Hi All,

I had email conversation with cloudera certification about same query below is the response i got from cloudera certification team,

During the exam, it is possible to get templates so that all coding is not done from scratch.

https://www.cloudera.com/more/training/certification/cca-spark.html

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.

According to certification team knowldge of Scala and python is must for the examination.

To clarify a bit on the Scala and Python questions here is a snippet from our community knowledge article Cloudera Certifications FAQ:

Q - Do I need to know both Scala and Python for the CCA Spark and Hadoop Developer (CCA 175) Certification?

A - 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.

@ashishdiwan03

oh ok! thank you for the update! (the info that I got from the other community may be wrong ) but it is good that you have mailed cloudera for the confirmation...

Re: CCA 175 Revised Syllabus

saranvisa — Tue, 30 May 2017 19:04:18 GMT

@Adarsh03

To my knowledge, no need to create a jar file.. Instead you need to store all your commands in a notepad and execute one by one in spark shell command line

@ashishdiwan03

FYI, i got multple confirmations from a different community where the people confirmed that there is no template provided.

Cloudera Stmt: it is possible to get templates so that all coding is not done from scratch.

Also according to cloudera statement, there is no confirmation that template will be provided, they are saying it is possible but not mandatory. So even template provided, it is not mandatory to use the template , I mean if you are familiar with Scala but you got Python template then it is not mandatory to use Python template, instead you can delete the template and write code in Scala --Because template is provided to help you but not to force you to follow either Python/Scala. All they need is your result

So I want to reconfirm that to appear for CCA175 - it is good to know both Scala/Python but If you are master in Scala but don't know python, Still you can appear for the exam and write your code using Scala

Hi,

my doubt is if the available eclipse in the cluster contains scala nature.

i'm asking this because i've downloaded CH 5.10, and the bundle eclipse does not support scala.

Re: CCA 175 Revised Syllabus

saranvisa — Wed, 07 Jun 2017 17:59:42 GMT

@gsjunior86

You need to apply scala plug-in in Eclipse (Scala Perspective). Scala is not a default one

Re: CCA 175 Revised Syllabus

gsjunior86 — Wed, 07 Jun 2017 22:02:35 GMT

@saranvisa, yeah sure, no probleam with that.

My question is if in the cluster available for the test, the plugin will come installed,

because i think that external access will not be available, isn't?

Re: CCA 175 Revised Syllabus

saranvisa — Thu, 08 Jun 2017 14:38:41 GMT

@gsjunior86

You don't need to use IDEs like eclipse, InteliJ, etc... also no need to create jar as part of the exam. You can login as spark-shell (or) pyspark and execute your commands one by one. All they need is your result and this will save your time

I understand this is an old thread, hopefully my reply here will still get attention.

My questions are:

1. The above discussion is confusing: the "marked" answer says template will be provided (not mandate to be used), the other user says multiple channels confirmed to him/her that no template was provided in the actual exam, which is true?

2. Is Flume excluded from the exam?

3. Is Internet browsing like Google allowed in the exam? I ask this question because often the case we come to the need to check documentation user guide for each component like Spark, Hive, etc.

Thank you.

Hi @axie,

If you look at the CCA175 certification page you will see the following wording on templates

Exam Question Format

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.

As for Flume and availability of documentations you can see at the bottom of that page (I put Flume items in red):

Exam delivery and cluster information

Thanks Mr. Jervis,

There have been a lots complaint about the cluster/VM performance, do you have any update from the certification department, I know you have been talking to them about those complaints.

Re: CCA 175 Revised Syllabus

cjervis — Tue, 30 Jan 2018 20:59:58 GMT

The certification team advised me that they have reviewed each of the exams they were contacted about and didn't find any performance issues.

axie — Tue, 13 Feb 2018 03:22:09 GMT

I am doing some practices, for some questions, there could be various solutions, for example, I can use RDD operations to do some filtering, sorting, and grouping; with DataFrame and SparkSQL, it is even easier to me to get the same result.

My question is will there be a requirement in the exam that some questions must be resolved using RDD, not DataFrame+SparkSQL. or vice versa?

Thank you.
