 Description  « Hide
Hive is a data warehouse built on top of flat files (stored primarily in HDFS). It includes:
  • Data Organization into Tables with logical and hash partitioning
  • A Metastore to store metadata about Tables/Partitions etc
  • A SQL like query language over object data stored in Tables
  • DDL commands to define and load external data into tables

Hive's query language is executed using Hadoop map-reduce as the execution engine. Queries can use either single stage or multi-stage map-reduce. Hive has a native format for tables - but can handle any data set (for example json/thrift/xml) using an IO library framework.

Hive uses Antlr for query parsing, Apache JEXL for expression evaluation and may use Apache Derby as an embedded database for MetaStore. Antlr has a BSD license and should be compatible with Apache license.

We are currently thinking of contributing to the 0.17 branch as a contrib project (since that is the version under which it will get tested internally) - but looking for advice on the best release path.
