I download dist.tgz. When I start HIVE, I got 

"WARN fs.FileSystem: "localhost:9000" is a deprecated filesystem name. Use "hdfs://localhost:9000/" instead.

>             Project: Hadoop Core
>          Issue Type: Wish
>          Components: contrib/hive

> 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.
