Subject [jira] Commented: (HIVE-976) test outputs should compare the file/directory for sampling
Date Thu, 31 Dec 2009 00:27:29 GMT

    [ https://issues.apache.org/jira/browse/HIVE-976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795504#action_12795504

John Sichi commented on HIVE-976:

Regarding input40.q:  yes, I get a diff because the results from this query come out in a
different order:

select * from tmp_insert_test_p where ds = '2009-08-01';

A big chunk of rows moves in the output.  Diff-based testing doesn't really work if it's not
possible to add order by uniformly, does it?

> Currently, all lines starting with file: are ignored.
> It means that
> file:/Users/heyongqiang/Documents/workspace/Hive-Test/build/ql/test/data/warehouse/srcbucket/srcbucket0.txt
> and
> file:/Users/heyongqiang/Documents/workspace/Hive-Test/build/ql/test/data/warehouse/srcbucket
> are same - that is not good because it will hide some of the optimizations of sampling.
> This should be changed to compare the last token.
