Subject [jira] [Commented] (HIVE-600) Running TPC-H queries on Hive
Date Fri, 06 Apr 2012 01:46:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13247949#comment-13247949

alex gemini commented on HIVE-600:
----------------------------------

I guess the Q9 failed is because hive set mapred.min.split.size=536870912, the default jvm
setting for task launch is 200M, so it failed,remove this setting or set jvm memory for a
larger value would be nice.

> The goal is to run all TPC-H (http://www.tpc.org/tpch/) benchmark queries on Hive for
two reasons. First, through those queries, we would like to find the new features that we
need to put into Hive so that Hive supports common SQL queries. Second, we would like to measure
the performance of Hive to find out what Hive is not good at. We can then improve Hive based
on those information. 
> For queries that are not supported now in Hive, I will try to rewrite them to one or
more Hive-supported queries.
