Subject [jira] Commented: (HIVE-189) Various TestCliDriver tests fail
Date Wed, 14 Jan 2009 18:29:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12663831#action_12663831

Ashish Thusoo commented on HIVE-189:
------------------------------------

On thinking more about this, I think we should change the test for input3_limit.q to make
it deterministic. Instead of

INSERT OVERWRITE TABLE T2 SELECT a.key, a.value from T1 a LIMIT 20;

We should have

INSERT OVERWRITE TABLE T2 SELECT * FROM (SELECT * FROM T1 DISTRIBUTE BY key SORT BY key, value)
T LIMIT 20;

SELECT * FROM T2

That would ensure that the rows that we get are top 20 rows.

The order in which these files are processed are controlled by hadoop, so I don't think we
have much control on whether kv1.txt gets processed first or kv2.txt.

Thoughts?
