A Study of Hadoop Developers from Karmasphere

Karmasphere, a a Big Data Intelligence (BDI) software company bringing Apache Hadoop power to developers and analysts, has published the results of a survey among Hadoop users. The report can be downloaded from ☞ here (PDF).

Interesting notes:

  • Within  a  year,  86%  of  projects  have moved to either active development or production
  • In 68% of the cases, the first use of Hadoop was not mandated by someone higher in the organization
  • the top reasons for using/evaluating Hadoop:
    • mine data for improved business intelligence
    • reduce cost of data analysis
    • log analysis
  • top challenges in adopting Hadoop:
    • steep learning curve
    • hiring qualified people
    • availability of appropriate products and tools[1]
    • enough information on how to get started
  • top programming challenges:
    • debugging Hadoop jobs
    • monitoring Hadoop jobs
    • insufficient educational resources

Definitely a lot of data points and possible conclusions, so ☞ check it yourself (PDF).

  1. That’s really interesting considering how rich is the Hadoop tools ecosystem  ()
