Prasad Chakka commented on HADOOP-3601:
---------------------------------------
Hi lengwuqing
Here are some answers that might make the above steps little easier...
1: Compiling
I think just copying the facebook-hive.tar.gz to src/contrib/hive and then
doing 'ant package' from hadoop-0.17.2.1 directory should create the necessary
packages for Hive in build/contrib/hive/dist and also where Hadoop expects.
(Steps 4 & 5 can be done by just going 'ant package')
2: For step 4) just do 'ant build-grammar' from src/contrib/hive/ql directory
that would generate a antrl grammar code. You might also need to do 'ant
gen-test' if you want to see the test code.
4: Did you mean that Insert Overwrite is not working correctly? Which query is
computing incorrect results?
Thanks,
Prasad

> 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.
