[jira] [Commented] (HIVE-5129) Multiple table insert fails on count(distinct)

["Vikram Dixit K (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-5129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13745735#comment-13745735 ] 

Vikram Dixit K commented on HIVE-5129:
--------------------------------------

[~navis] This issue is related to HIVE-4692. I have attached a patch which retains the same behavior as was before that patch without affecting the test added as part of it. However, I am not sure what else is affected by this down stream. I have started to run the unit tests to make sure I haven't broken other things. It would be great if you could take a look and provide feedback on this. Please let me know if you have a better approach in mind.

Thanks!
