Zheng Shao commented on HADOOP-3601: ------------------------------------ The publists.facebook.com link for hive mailing list is deprecated. Please see http://hadoop.apache.org/hive/mailing_lists.html for details on the new mailing lists. > Hive as a contrib project > ------------------------- > > Key: HADOOP-3601 > URL: https://issues.apache.org/jira/browse/HADOOP-3601 > Project: Hadoop Common > Issue Type: Wish > Affects Versions: 0.19.0 > Environment: N/A > Reporter: Joydeep Sen Sarma > Assignee: Ashish Thusoo > Priority: Minor > Fix For: 0.19.0 > > Attachments: ant.log, hive.tgz, hive.tgz, hive.tgz, 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
