So while going through Edureka Big Data Certification course training, you will be working on multiple use-cases as well as real time scenarios, which will help you in clearing various Hadoop certifications offered by Cloudera and Hortonworks.

Cloudera Certifications

The CCA exams test your basic foundation skills and set forth the groundwork for a candidate to get certified in CCP program.Edureka’s Big Data certification course helps you to get deep learning about all the Big Data tools and application. Cloudera has 3 certification exam at CCA level (Cloudera Certified Associate).

Cloudera Certifications - Hadoop Certification - Edureka

  1. CCA Spark and Hadoop Developer 
  2. CCA Data Analyst
  3. CCA Administrator 

CCA Spark and Hadoop Developer (CCA175)

The person clearing the CCA Spark and Hadoop Developer certification has proven his core skills to ingest, transform, and process data using Apache Spark and core Cloudera Enterprise tools. The basic details for appearing CCA 175 are:

  • Number of Questions: 8–12 performance-based (hands-on) tasks on Cloudera Enterprise cluster
  • Time Limit: 120 minutes
  • Passing Score: 70%
  • Price: USD $295

Each CCA question requires you to solve a particular scenario. In some cases, a tool such as Impala or Hive may be used and 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 of functional code. This template is written in either Scala or Python.

It is not mandatory to use the template. You may solve the scenario using a programming language. But however, you should be aware that coding every problem from scratch may take more time than is allocated for the exam.

Your exam is graded immediately upon submission and you are e-mailed a score report the same day of your exam. Your score report displays the problem number for each problem you attempted and a grade on that problem. If you pass the exam, you receive a second e-mail within a few days of your exam with your digital certificate as a PDF, your license number, a LinkedIn profile update, and a link to download your CCA logos for use in your social media profiles. It is easy to pass the CCA exam after you have completed this Edureka’s Big data certification training course developed by top experts in the Hadoop platform. Learn more about Big Data and its applications from the Data Engineer certification.

Now, let us know the required skill set for clearing CCA 175 certification.

  • Language: English

For each problem, you must implement a technical solution with a high degree of precision that meets all the requirements. You may use any tool or combination of tools on the cluster. You must possess enough knowledge to analyze the problem and arrive at an optimal approach given the time allowed. 

Below are the required skill set for clearing CCA Data Analyst certification.

Required Skills:

Prepare the Data

Use Extract, Transfer, Load (ETL) processes to prepare data for queries.

  • Import data from a MySQL database into HDFS using Sqoop
  • Export data to a MySQL database from HDFS using Sqoop
