Big data means big business. Countless companies are digging into data acquisition, storage, analysis and trend-spotting on a scope and scale unlike anything ever before. Along with those companies, a new generation of software platforms, analysis tools, and related professional skills and knowledge present unparalleled opportunities for interesting and high-paying work for IT professionals with the "right stuff" to play on the big data field. Cloudera remains on our list as one of the top big data certification providers, and Hadoop certification is one of the top four big data platforms in use today.
Cloudera is a company that specializes in mega data collections built around the Apache Hadoop platform to create what it calls "enterprise data hubs." Such hubs enable customers to create information-driven organizations, where Cloudera provides a platform for enterprise-ready data management. This platform is designed to provide the tools to extract the most value from your customer data.
Although Hadoop is a free, open-source platform, Cloudera adds substantial value by providing strong security, policy-driven data governance, formal system management, product support and lots of important system integrations to bring all data sources together under its umbrella. Cloudera offers enterprise and express versions of its Cloudera Distribution. This includes Cloudera Apache Hadoop, usually abbreviated CDH, with varying license models. It provides a no-charge, unsupported download of core CDH software too.
Cloudera invented itself around a clutch of high-flying super geeks, including Amr Awadallah, who built one of the first-ever business units based on Hadoop analysis for Yahoo. Jeff Hammerbacher did likewise for Facebook, for analysis of that company's humongous collections of user data. Other Cloudera heavyweights include Doug Cutting, the software architect who wrote the initial version of Hadoop in 2004, and Oracle executive Mike Olson.
Cloudera has been in business since 2009. It continues to attract a growing base of high-profile customers. The company has experienced substantial growth, earning recognition as one of the fastest-growing companies in North America on the Deloitte Technology Fast 500 for 2018. For Q4 of the company's 2018 fiscal year, it reported a 42% increase over earnings for the same quarter in its previous year. Estimates of Cloudera's overall valuation range as high as $5 billion. There's dollars in them data!

The exam costs $295 and includes eight to 12 performance-based, hands-on problems that the candidate must solve in 120 minutes. While there are no formal prerequisites, candidates must know how to code in Python and Scala and run code on a CDH5 cluster. Candidates must score at least 70% on the exam to pass. To maintain their certification status, candidates must retest every two years.
Cloudera's CCA Administrator aims at IT professionals charged with configuring, deploying, maintaining and securing Cloudera Enterprise clusters for production or other enterprise uses.
A single exam (CCA131) is required to obtain the credential, which costs $295. Skills tested include HDFS, Cloudera Manager, Hadoop cluster planning, configuration, installation and administration, resource management, and logging and monitoring. The exam costs $295 and includes eight to 12 performance-based, hands-on problems that the candidate must solve in 120 minutes. There are no formal prerequisites.

Cloudera's Certified Professional Data Engineer (CCP Data Engineer) targets individuals capable of developing reliable, scalable solutions for big data workloads.
The CCP Data Engineer exam is a practical exam consisting of a set of five to eight customer-focused problems. The exam is designed to test skills required for successful big data engineers, including performing workflow-oriented tasks; analyzing data (showing the ability to write various queries, as well as create and read HCatalog and Hive tables from HDFS data); converting data values into new formats and rewriting to HCatalog, Hive or HDFS; and transferring data between internal clusters and external systems.
There are no prerequisites, but CCP Data Engineer candidates should be experienced in solution development and related skills and knowledge. This performance-based exam costs $400 and has a four-hour time limit. Credential holders need to retest every three years to maintain this certification.
