Hive is a data warehouse which provides SQL
like queries for data residing in HDFS. A RDBMS wrapper for files available
in HDFS.

Hive is strictly used for select. NO
UPDATE/DELETE is provided. It makes it a data warehouse. The SQL code written
in Hive eventually turns into MapReduce code and is implemented on database.
