Subject [jira] [Commented] (DRILL-612) TPCH: query 06 verification fails
Date Thu, 29 May 2014 16:59:07 GMT

    [ https://issues.apache.org/jira/browse/DRILL-612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14012538#comment-14012538

Jacques Nadeau commented on DRILL-612:
--------------------------------------

Spot manual verifications shows correct results other than floating point variations with
latest master.  Please update verification framework to correctly identify these.

> 1. Set up drill test framework (see https://github.com/zhiyongliu/incubator-drill/tree/master/testing)
and generate TCP H dataset with a scale factor of about 500MB.
> 2. Query file (modified from original by drill dev, and further modified as follows):
> select
