If by demand you mean in the jobs market, I can only give highlights from a much larger set of regular and ongoing research into the jobs market and how that might map to our (Cloudera's) certifications which are much more narrowly focused than our training offerings. If you look at this year's labor market (job listings across all job boards, etc.): - Apache Hadoop fars outranks all other terms (very general term) and is the 67th most referenced term in the market, which includes words/phrases like "Outlook" and "Word" and other products that nearly EVERY job listings includes. Of those Apache Hadoop jobs - 2000 currently mention Cloudera specifically (as in "must have experience with Cloudera" or "must be Cloudera certified") - Java far outranks all other requirements (mentioned in 60% of the job listings) - SQL is mentioned next (35%), though many of these also include Java or NoSQL or "at least one other language" usually Python - Python is next (34%) - Then it goes to Linux, Unix, NoSQL experience, Hive, Pig (though presumably the SQL would bolster the HIve/Pig) Of those that use Hadoop in the requirements, the job titles rank out. - Sofware Engineer - Java Software Engineer - Data Architect - Data Scientist - Solutions Architect - Data Analyst Of the 41,530 job listings in the US that include the term "Big Data" (expanding it out of Hadoop specific) the job titles themselves rank like this) - Software Engineer ranks first (3x more than anything else) - Data Architect - Java Software Engineer - Software Development Engineer - Solutions Architect - Data Analyst - Java Engineer - Data Scientist So you can see where some of those job titles are most prevelant. Anyway, there's some raw data. I could spend 1000 hours interpreting it and cross-referencing what it means but there's a sense of things.
