--------------------------------------
> Another option would be to create a sandbox sub-project.
> A sandbox project that meets some bar could become a sub-project.
What's the bar? Releases need to be approved by the Hadoop PMC, and, more
generally, the PMC must monitor all activity in the project. I don't see how a
sandbox designation would help oversight.
We don't need more options. We have well-understood options that serve us
well: core, contrib, sub-projects, TLPs, etc. We need to choose one. The Hive
folks seem happy with contrib. I'm willing to try that. If it becomes a
problem, we'll switch to something else.
> Hive as a contrib project

> Key: HADOOP-3601
> URL: https://issues.apache.org/jira/browse/HADOOP-3601
> Project: Hadoop Core
> Issue Type: New Feature
> Affects Versions: 0.17.0
> Reporter: Joydeep Sen Sarma
> Priority: Minor
> Attachments: HiveTutorial.pdf

> Original Estimate: 1080h
> Remaining Estimate: 1080h

> 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.
