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.

The current version of the exam is not using templates. We have removed a question to make the exam shorter, but currently you must write everything from scratch.

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.

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 · ‎01-24-2017

Cloudera has released a new certification exam for Data Analysts - CCA159. This is an entry level CCA certification, similar to CCA175. Instead of a focus on Spark and development, the focus is on using Impala/Hive to access the metastore and create SQL queries to generate reports from information in tables. See all of the required skills for the exam at: http://www.cloudera.com/training/certification/cca-data-analyst.html This exam follows all of the same learning objectives as the Cloudera Data Analyst course, if you need additional practice with the required skills: http://www.cloudera.com/training/courses/data-analyst-training.html?course=data-analyst&loc=online

The CCP exam, including the CCP:Data Science exam do not force you to follow a particular tool or programming language. The explain a scenario and ask you to come up with a set of results based on the problem description. The DS200 Solution Kit is the solution that our data scientists came up with during one of the early exams. You can choose any language to work in. They chose Python. This was before Spark was even supported on our clusters. It is merely there to be reprentative of the types of questions that are asked during the exam, not to show you how you must answer the new exam. You may install any tools and any libraries that you would like to use during the DS exam. There are dozens of things already installed, that are detailed on the certification webpages. Currently, the cluster is open to the internet and there are no restrictions on tools you can install or websites or resources you may use.

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 · ‎05-26-2016

The results are typically sent within a few hours. I just made sure that your results were sent out.

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 · ‎05-13-2016

The DE-575 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.

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.

The Data Scientist exam is a proctored, remote exam. It does not use Virtual Box or a virtual machine; it has a completely different environment. During the exam you will have access to the Internet and can install any tool that you would like to use.

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 · ‎05-02-2016

Sublime is installed on the cluster. Maven is installed on the cluster. The scala plugin for Eclipse is not installed. Your solution would not work. We block Internet access to all sites except the ones we have listed, so you cannot download additional repositories. But everything that you need to build should already be there.

juddimal · ‎04-28-2016

Yes. Both Spark and Hive are tools that can be used in the exam. Transforming data, including sorting, is a skill that we recommend you understand. So you should understand the different combinations. The clusters are running CDH5.3.2 which do not support Spark SQL.

juddimal · ‎04-28-2016

The CCA-175 is currently using CDH5.3.2 That contains Hive 0.13.1 http://www.cloudera.com/training/certification/cca-spark.html

juddimal · ‎04-26-2016

SBT and spark-submit will be installed on the cluster. You are free to use them as tools. In the CCA-175 exam, in order to speed up development you should expect that most coding questions will have a template provided with some of the code so that you do not have to write everything from scratch. If Cloudera provides a template, there will be an executable script written that can run that template.

juddimal · ‎04-23-2016

In the cases when you are given a template, you will be given a script in order to run that tempate.

juddimal · ‎04-23-2016

It sounds like you have a very good plan. The Cloudera Hadoop Administrator training http://www.cloudera.com/training/courses/administrator-training.html?course=administrator&loc=online would give you a push in the correct direction and have hands-on exercises for practicing the material. Otherwise, Hadoop Operations is probably your best bet.

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

juddimal · ‎04-18-2016

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