  == What is Hive ==
  Hive is the next generation infrastructure made with the goal of providing tools to enable easy data summarization, adhoc querying and analysis of detail data. In addition it also provides a simple query language called QL which is based on SQL and which enables users familiar with SQL to do ad-hoc querying, summarization and data analysis. At the same time, this language also allows traditional map/reduce programmers to be able to plug in their custom mappers and reducers to do more sophisticated analysis which may not be supported by the built in capabilities of the language.
