Cloudera's idea of Hadoop as an enterprise data hub is bold, but the reality is quite different. 　　The Hadoop distance has a long way to go before other big data solutions are eclipsed. When you have a hammer big enough, everything looks like nails. This is one of the many potential problems that Hadoop 2.0 faces. For now, the biggest concern for developers and end-users is that Hadoop 2.0 has massively modified the framework for large data processing. Cloudera plans to build Hadoop 2.0 ...
