Gunther Hagleitner updated HIVE-4179: ------------------------------------- Attachment: HIVE-4179.3.patch Adjusted fix per Navis' instructions. I've also checked other union_remove* testcases and updated their golden file after verifying. There are still failures in some of the union_remove testcases - but I think those are unrelated and I will open separate jiras for them (8,9,10,12,13,24) > NonBlockingOpDeDup does not merge SEL operators correctly > --------------------------------------------------------- > > Key: HIVE-4179 > URL: https://issues.apache.org/jira/browse/HIVE-4179 > Project: Hive > Issue Type: Bug > Reporter: Gunther Hagleitner > Assignee: Gunther Hagleitner > Priority: Critical > Fix For: 0.11.0 > > Attachments: HIVE-4179.1.patch, HIVE-4179.2.patch, HIVE-4179.3.patch > > > The input columns list for SEL operations isn't merged properly in the > optimization. The best way to see this is running union_remove_22.q with > -Dhadoop.mr.rev=23. The plan shows lost UDFs and a broken lineage for one > column. > Note: union_remove tests do not run on hadoop 1 or 0.20. -- This message is automatically generated by JIRA.
