It might be a bit off topic but does anyone here has experience with BigData ? Tools like Hadoop for example ? I wonder if it worth investing time learning that toolset or if eventually only SAS or SAP are relevant. It at this point only for my own "entertainment" and learning but I think good to have some basics for what might come across in my company the next years. My current pool of big data: firewall log, network traffic and a number of folding logs should give enough "big data"-like source information to play around with. Any recommendation on books/kindle to read or online trainings /webinars ?
