https://www.cloudera.com/about/training/certification/faq.html What am I responsible for during the exam? These are practical exams. During the exam you will be asked to evaluate a scenario and implement a solution. You are responsible for everything necessary to generate that solution, such as writing code, configuring tools, and debugging any issues. You may use any approach or tools on the cluster that will produce your solution. Only the results will be graded.

Kabali, All certification requests are processed by certification@cloudera.com I can see that Dora in the support team has already written you today and forwarded your request to the technical team. All outstanding certificates are scheduled to be sent out in the next 24 hours.

Cloudera courses give you background and information to be successful at a particular job role. Certification exams attempt to test your skills at a particular job role. The testing objectives on the exams are similar to the learning objectives in the course. However, Cloudera training courses are not "prep courses" for the exam. There is not always a 1-to-1 correlation between presented materials/exercises and the exam. Suggested prerequisite training courses for our exams do NOT guarantee a passing score and are NOT be considered the only preparation required to successfully complete the exam. Since the exam webpages give you explicit required skills that will be tested, I would suggest that candidates practice those skills outside of the classroom experience before taking any exams. More specifically, for this exam. 1) Should I have Linux or Cloudera administration experience? Yes, and yes. 2) CM or command-line? Cloudera Manager is provided during the CCA131 exam so you may use either.

Effective immediately, we are phasing out CCP Data Scientist. We will continue to work with those candidates who have passed one of the exams to allow them to complete their evaluation but will no longer accept new candidates. The data science field continues to see rapid change and growth. You’ll hear exciting product announcements from Cloudera in the weeks ahead with the intent to make data science workloads run more easily on Cloudera Enterprise, and to reach out to a broader data science community than the ones for whom this program was designed. We will continue to invest in substantial curriculum updates to reflect the changing product and market dynamics, and we’ll continually evaluate whether and when we should bring to market a redesigned certification at a future date.

Content changes are made on the exams every week; questions are removed, questions are added, and questions are modified. With the release of the Data Analyst exam, there is less need to test "logging into Impala" questions, so CREATE TABLE questions have been moved to the Analyst exam. With the release of a new version of Spark, it is easier to test "using tables as a data source" questions, so expect some questions to have a table instead of just a directory of data files as the inputs. There has always been an Analysis section on the Required Skills for this exam. All that was done was to update that section to focus more on Spark. This is not a new exam, this is a minor update. We are updating the version of CDH used with our exams. Data Analyst uses CDH5.9.1. All other exam continue to be on CDH5.3.2. This announcement is that Spark & Hadoop Developer has been converted over to CDH5.10.0. The CCA175 Spark exam is being testing in development with Spark 1.6 now. When we are satisfied that the new version does not break any existing questions, we will be moving the new version into production. We are not announcing a date for when the exam content changes. If you wish to make sure that you your exam is with the latest versions of our products, wait to schedule your exam until April. If you wish to take the exam with the old version then schedule immediately. We will be making changes as soon as we can guarantee a proper exam and without any further warning.

juddimal · ‎03-07-2017

An update was made to the CCA175 Spark and Hadoop developer certification webpage today. There are two changes that are being announced. The cluster has been updated to CDH5.10.0 with all of the ecosystem changes that entails, including the use of Spark 1.6 The release of the Data Analyst exam means that DDL questions have been removed from the CCA175 exam. There are still questions interacting with the metastore, but they will be more related to queries done from Spark SQL than creating tables using DDL. See the Required Skills section of the webpage. Exams taking in the next few days will still get the old exam and cluster, but this is a notification of changes for later this week.

juddimal · ‎05-28-2016

CDH4 and CDH5 are Cloudera specific releases. They are not Cloudera specific tools. There will not be questions about Cloudera Manager. There will not be questions about Cloudera Director. There will not be questions about Cloudera Navigator. Each of these products begin with the name "Cloudera", and as such are Cloudera specific tools. There will be questions about daemons. This is a CDH5 exam. If asked what daemons need to be running, you must answer with the daemons that are needed in CDH5. If you chose the daemons that were present in CDH4, you will be marked as wrong (assuming that the daemons changed between versions).

juddimal · ‎05-24-2016

Cloudera attempts to make these industry-wide certifications, not just on the CDH platform. There are no questions that are specific to Cloudera Manager or any other Cloudera specific tool. The CCA-500 is specific to the CDH5 release. It will not ask questions that are dependent on minor releases, ie there are no questions that will ask the differences that may occur between CDH5.6 upgraded to CDH5.7, but there may be questions that require you to know the differences between CDH4 and CDH5.

juddimal · ‎05-16-2016

In the case of an external library, no. We are trying to give you flexibility to solve the problems in whatever way that you see fit, but since there may be dozens of ways to solve the problem, there is no way that we could provide a dozen different versions of the library. For example, if the objective we are trying to test is your ability to use a UDFs, then you will need to use a tool that supports UDFs, such as Hive or Impala.

juddimal · ‎05-11-2016

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: Use Data Definition Language (DDL) to create tables in the Hive metastore for use by Hive and Impala. 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.

juddimal · ‎05-09-2016

The CCA-175 exam is the Developer exam and maps to the Developer training: http://www.cloudera.com/content/dam/www/static/documents/datasheets/developer-training-for-spark-and-hadoop.pdf The DE-575 exam is our Data Engineering exam. It includes topics that are coved in the Big Data Applications course: http://www.cloudera.com/content/dam/cloudera/Resources/PDF/Datasheet/Cloudera_Training_Designing-and-Building-Big-Data-Apps_103.pdf I would like to point out that the DE-575 is a CCP (Cloudera Certified Professional) exam. That means that it is our mastery level exam in the developer track. It is meant for people that have industry knowledge and exerience working in the field; we do not provide a prep-course for taking that exam.

The vnc software that will set up your remote desktop will be using port 20443. I don't know of any way to test that your company firewall will allow access to that port.

juddimal · ‎05-03-2016

You are making a connection from your browser to a remote cluster running in AWS. Your browser will become a virtual desktop, complete with IDEs, teminals, etc. If you want a free environment to practice in, you can download the Cloudera Quickstart VM. Here is a link to the latest version: http://www.cloudera.com/downloads/quickstart_vms/5-7.html

juddimal · ‎04-21-2016

No, I don't know where that page is trying to take you. Where is that link? On a Cloudera page? My guess is that link is to an older Data Scientist exam. Details on the challenge that we currently have running can be found here: http://www.cloudera.com/training/certification/ccp-ds.html http://www.cloudera.com/training/certification/ccp-ds/exams.html

Certification exams are not taken at a testing center any longer. They are now taken online. http://www.cloudera.com/training/certification/faq.html

It means two things. First, there is a section of the required skills labelled Transform, Stage, Store. The exams will definitely focus on converting on thing to another, either through changing file formats or changing the records themself. Second, you are correct. If we give you a library, you should know how the tool you are using will allow you to use it. Any external library will be provided to you.

juddimal · ‎03-21-2016

SBT is not one of the packages that comes installed on the cluster.

juddimal · ‎03-20-2016

There are no exercises or practice exams for the new hands-on practical exams. Our Cloudera Developer Training for Spark and Hadoop teaches you all the skills to pass the exam and gives you days worth of hands-on practice. If you do not wish to take our training or cannot afford it, there are hundreds of free resources on the internet. For example, if I point my browser to the List of objectives from our website. I then copy the first objective and search on it, I get dozens of free docs and training on the skill. Objective: Import data from a MySQL database into HDFS using Sqoop • sqoop.apache.org docs on importing data using Sqoop • Importing Data into HDFS using Sqoop • Video demonstration of user importing data from MySQL to HDFS using Sqoop This can be done for any of our exams. Of course the quality of materials freely discovered on the internet differs greatly, as does the discount training vendors, which is why we only recommend Cloudera training.

juddimal · ‎03-14-2016

http://www.cloudera.com/training/certification/cca-spark.html Check the required skills. If it is not in that list, then there will not be a question regarding that topic.

1) The Developer course maps the the CCA175. The CCP DE575 is a difficult exam meant to test development mastery. A data analyst taking this exam would be very unhappy. DE575 most closely maps to our Big Data Applications course (plus some years of experience). We currently do not have a certification path that maps to our Data Analyst course, but you should continue to watch the website for announcements. http://www.cloudera.com/training/certification.html 2) Look on the community site for the subject below this one labelled "Spark Scala AND Python" https://community.cloudera.com/t5/General-Questions-Training/CCA175-Spark-Scala-AND-Python/m-p/36070#U36070 3) The testing objectives for our certifications are close to the learning objectives for the courses, and the courses have exercises that will help you practice for the practical nature of the exam. The training is not required, however. 4) There is no Java on the exam, but there is development work that needs to be done. See question 2. You can also see all of the skills required at: http://www.cloudera.com/training/certification/cca-spark.html

juddimal · ‎02-04-2016

The details about the exam are on Cloudera's website: http://www.cloudera.com/training/certification/cca-spark.html Cloudera offers a course that covers these topics and give you hands-on exercises to practice these skills: http://www.cloudera.com/training/courses/developer-training-for-spark-and-hadoop.html?course=developer-training-for-spark-and-hadoop&loc=online There are multiple books covering the basics of Hadoop, including Hadoop: The Definitive Guide The website also shows you all of the skills that will be tested, so you could use that as a basis for your own self study.

juddimal · ‎01-26-2016

Support for Spark SQL is being added into CDH5.5 As of today, the exam is running on CDH5.3.2 So the answer is "not yet", but that will almost certainly change in the near future. Watch the Cloudera website: http://www.cloudera.com/training/certification/cca-spark.html The list of required skills should give you knowledge of what technologies you will need to know.

juddimal · ‎01-20-2016

Once you submit the exam it will be graded. An email will be sent to you the day that you take the exam that is a score report. It will show each problem that you attempted and whether you passed or failed. If you fail a question, it will tell you what criteria you did not answer correctly. If you passed, within a few days after that, you will recieve another email that contains your certificate. It will be a PDF that you can print. No hardcopy will be provided.

juddimal · ‎01-19-2016

You can expect that major changes to CDH will also change the version that is on the clusters. There is not a schedule for when changes will be applied. I would watch the Cloudera certifcation webpages for updates. http://www.cloudera.com/content/www/en-us/training/certification/cca-spark.html

juddimal · ‎01-19-2016

The cluster will use a "recent" version of CDH. Currently that is 5.3.2. In the future, the answer is yes; the cluster will be upgraded to a newer version of CDH. I would not expect an immediate change when Cloudera releases new versions of CDH, as there will need to be a period of testing the exam on the newer versions. In general, however, you should not care what version you are using. As this is a developer exam, there will likely be no change to the solution you provide regardless of the underlying system. Creating a table in Impala is probably not going to change based on the cluster. I understand there may be some effects for major changes, such as CDH 5.5.0 and the addition of tools such as Spark SQL, but changes like that will be announced on the Cloudera certification webpages.

juddimal · ‎01-19-2016

Because of the length of the Data Science certifications, you are allowed to take breaks. That is not necessarily true with our shorter exams. Work with your proctor during the exam to get some time away from the computer.
