--------------------------------------------------

  = What is Hive =
- [[http://hadoop.apache.org/hive/|Hive]] is a data warehouse infrastructure built on top
of [[.|Hadoop]]. It provides tools to enable easy data ETL, a mechanism to put structures
on the data, and the capability to querying and analysis of large data sets stored in Hadoop
files. Hive defines a simple SQL-like query language, called QL, that enables users familiar
with SQL to query the data. At the same time, this language also allows programmers who are
familiar with the MapReduce fromwork to be able to plug in their custom mappers and reducers
to perform more sophisticated analysis that may not be supported by the built-in capabilities
of the language.

  Hive does not mandate read or written data be in the "Hive format"---there is no such thing.
Hive works equally well on Thrift, control delimited, or your specialized data formats.  Please
see [[/DeveloperGuide#File_Formats|File Format]] and [[http://www.slideshare.net/ragho/hive-user-meeting-august-2009-facebook|SerDe]]
in [[/DeveloperGuide|Developer Guide]] for details.
