Become a Vital Asset to an Organization: Get a Big Data Hadoop and Apache Spark Developer Certification

The modern-day digital world is ever changing. Over time, technologies have come a long way and there’s no doubt that they will continue to grow, accelerate and transform businesses for the foreseeable future. As businesses turn fast-paced and technologies go through rapid evolution, massive amounts of data get generated every day. Therefore, there is a compelling need for big data technologies like Hadoop to store and analyze the data.

Having just the data is futile if there’s no expertise to analyze it. So there is definitely a need for skilled professionals who possess the ability to comprehend data patterns and come up with insights to benefit the business. For this reason, job opportunities in the field are many, and with proper training, any individual can master the right set of analytical skills to boost up a company’s business as well as their career.

Hadoop Certification and Its Value in Career Building

For individuals looking to build a career in the big data field, having a Big Data Certification from the leading Hadoop vendors like Hortonworks, Cloudera or IBM is a must. This helps candidates to add value to their profile and have a better chance of highlighting their skills to their employers and clients.

As Hadoop certifications are expensive, it is critically important to consider the quality of the certification and demand in the market. Having a credible Hadoop certification boosts up your chances of getting into a Hadoop job, gain experience and further advance your big data career. Moreover, the certification also proves that you are not new to the best practices in the big data industry and have working knowledge in the field.

Simplilearn’s Big Data Certification Training entirely covers up the concepts and curriculum as per the industry standards so that you can clear the certification program easily.

Cloudera: The Most Popular Hadoop Certification

While there are many Big Data Hadoop certifications in the market, Cloudera seems to be the most popular choice among Hadoop professionals. The Hadoop certifications that Cloudera offers are as follows:

  • Cloudera Certified Professional (CCP) – CCP certification is a performance-based certification that tests a candidate’s analytical skills. It is done through two exams, CCP Data Engineer and CCP Data Scientist.
  • Cloudera Certified Associate (CCA) – It also has two different exams, CCA Hadoop and Spark Developer and Cloudera Certified Administrator for Apache Hadoop, aimed at evaluating a candidate’s Hadoop and Spark knowledge.

As Cloudera is the leading player in the big data and data science market, going for a Cloudera Hadoop Certification will definitely upgrade a candidate’s skills to leverage big data for analytics in start-ups as well as multinational companies. Here, candidates understand the fundamental components existing in the Hadoop and Spark ecosystem. Moreover, it has been found that Cloudera Hadoop certified professionals do better in getting pay hikes and promotions as compared to their peers.

Eligibility Criteria

There are no such eligibility criteria to take any Cloudera certification exam. However, people looking to pass the Cloudera Apache Hadoop and Spark Developer Certification exam might have to consider learning some basic programming skills and concepts of Java. Hadoop is based on the Java platform as it was originally developed by Apache, so having some prior knowledge in Java will come in handy while grasping the terminologies and concepts associated with Hadoop programming. Working knowledge of SQL and basic user commands of Linux too would be of great help in studying Hadoop.

Last but not the least, the value of having a professional or equivalent degree from a university shouldn’t be underestimated. Reputed companies usually prefer their candidates from reputed universities, and without any degree, it might be difficult to make employers notice your skills.
