------------------------------------------
Hi Owen,
findbugs is not (yet) switched on for the Hive patch. So, if you run "ant
findbugs" from the top level, it won't run findbugs on src/contrib/hive yet. In
short, "ant findbugs" on the top level won't show any new findbugs warnings!
We plan to switch on findbugs (and also fix findbugs warnings) in a separate
follow-on JIRA. Hope that it ok with you.

> 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.
