Work on HIVE-6934 started by Hari Sankar Sivarama Subramaniyan. --------------------------------------------------------------- > PartitionPruner doesn't handle top level constant expression correctly > ---------------------------------------------------------------------- > > Key: HIVE-6934 > URL: https://issues.apache.org/jira/browse/HIVE-6934 > Project: Hive > Issue Type: Bug > Reporter: Harish Butani > Assignee: Hari Sankar Sivarama Subramaniyan > Priority: Critical > Fix For: 0.14.0 > > Attachments: HIVE-6934.4.patch, HIVE-6934.5.patch, HIVE-6934.6.patch, > HIVE-6934.7.patch, HIVE-6934.8.patch, HIVE-6934.9.patch, HIVE-6934.91.patch > > > You hit this error indirectly, because how we handle invalid constant > comparisons. Consider: > {code} > create table x(key int, value string) partitioned by (dt int, ts string); > -- both these queries hit this issue > select * from x where key = 'abc'; > select * from x where dt = 'abc'; > -- the issue is the comparison get converted to the constant false > -- and the PartitionPruner doesn't handle top level constant exprs corrcetly > {code} > Thanks to [~hsubramaniyan] for uncovering this as part of adding tests for > HIVE-5376 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
