Edward Capriolo commented on HIVE-1096: --------------------------------------- @Zheng I want to laugh now, but I spent about 4-5 hours trying to figure out what problem Hive was having. In general trying to debug the test cases through the testCliDriver can sometimes be difficult. Sometimes you get a decent stack trace, sometimes you get error code 11 or error code 2. I agree it ought to be fixed. Ok well now that I know the comment issue is not actually my problem I will remove the print statements and submit something that could go +1 > Hive Variables > -------------- > > Key: HIVE-1096 > URL: https://issues.apache.org/jira/browse/HIVE-1096 > Project: Hadoop Hive > Issue Type: New Feature > Reporter: Edward Capriolo > Assignee: Edward Capriolo > Attachments: hive-1096-2.diff, hive-1096.diff > > > From mailing list: > --Amazon Elastic MapReduce version of Hive seems to have a nice feature > called "Variables."
