  = What is Hive =
  Hive is a data warehouse infrastructure built on top of Hadoop that provides tools to enable
easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop
files. It provides a mechanism to put structure on this data and it also provides a simple
query language called QL which is based on SQL and which enables users familiar with SQL to
query this data. 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.
