Ashish Thusoo commented on HADOOP-3601:
---------------------------------------
Hi gleader,
Did you build it from hadoop sources or did you just download the dist.tgz? It
seems that the classpath is not properly set or the hive jars are not in your
classpath. Can you provide more details on how you set this up?

> 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.
