Subject [jira] [Commented] (HIVE-4342) NPE for query involving UNION ALL with nested JOIN and UNION ALL
Date Fri, 19 Apr 2013 23:55:15 GMT


Mihir Kulkarni commented on HIVE-4342:

I have updated the attachments which contain the command script to generate schema, the data
to be used with the command script and the exact query! I hope you are able to reproduce the
NPE with this information.
