SQL is one thing, not everything.
SQL is important, and that's why there have been so many announcements, but remember that the first and highest purpose for Hadoop is not to be an alternative platform for the same old structured data anlayses. Hadoop's higher use is correlating structured and unstructured data and finding new insights in variable data such as clickstreams, log files, mobile data, social data and more. YARN will enable multiple modes of analysis. Spark, for example, is aspiring to support machine learning, streaming analysis, SQL and other ways of analyzing data. So SQL is one thing, but not everything.
