But I can reproduce this with apache hadoop 0.20.2 and hive 0.7.0 and hive-0.10.x. I will try trunk. It is probably a bug in 0.20.2, but that is something we support. > CombineHiveInputFormat queries hang when table is empty and aggregation function is used > ---------------------------------------------------------------------------------------- > > Key: HIVE-4584 > URL: https://issues.apache.org/jira/browse/HIVE-4584 > Project: Hive > Issue Type: Bug > Reporter: Edward Capriolo > Priority: Blocker > > Running hadoop 0.20.2. Hive 0.10. The new default is combined input format. When you aggregate and empty table, or a table not empty with an empty partition the query produces 0 maps and 1 reduce and hangs forever. -- This message is automatically generated by JIRA.
