Top 10 LinkedIn Groups For Hadoop Experts

LinkedIn Groups

Where can you find a thriving community of thousands of Hadoop and Big Data experts and fans, exchanging best practices, and discussing the latest trends?  On the LinkedIn social network, you will find these experts active in discussion groups.  You will also find recruiters lurking in these discussion groups, looking for the next hot talent to scoop up for their companies, both Hadoop wizards and data scientists. [see disclaimer]

HadoopWizard.com’s Top 10 List of LinkedIn Groups for Hadoop (January 2013)

See below for the HadoopWizard.com‘s January 2013 list of top LinkedIn discussion groups for Hadoop.  These Hadoop-specific groups represented below have the most members and the most discussion activity.  (The group names and descriptions were provided by the group owners, and they vary a lot!)
