5. Big Data is not only about Hadoop:

If it’s big data then it’s Hadoop. That was the situation couple of years back, were Hadoop was the only known data analysis platform.  "Hadoop is a hot button initiative, with budgets and people being assigned to it," Kobielus pointed out.

But times have changed. HPCC Systems, the open source analysis platform of legal data research giants LexusNexus, was recently introduced in the tech world. Another recent platform for big data style job was provided by MarkLogic, who introduced its database, The MarkLogic Server for the big data. A recent hit in the analysis world is Splunk search engine which is used to analyze the data like server log data. "Whatever data you can extract from your logs, there is a good chance that Splunk can help," noted Curt Monash of Monash Research.
