Vikram Oberoi, a Big Data engineer from Cloudera, presented Hadoop use cases, explaining when and why you would use Hadoop. Here is Vikram's presentation, which he graciously provided for us - an note that he gave it a Houston-specific spin for the energy and medical applications.
Thanks to Erin Mynatt, also of Cloudera, for bringing Vikram from California and for coming from Denver, as well as for sponsoring the pizza & beer afterwards.
Thanks also to John Bland II for joining the group just in time. By the way, John is doing some awesome graphics work CNN, Fox, etc., so check him out!
