---------------------------------------
Summary: Fix type of constants in IN expressions to have correct
type
Key: HIVE-20617
URL: https://issues.apache.org/jira/browse/HIVE-20617
Project: Hive
Issue Type: Bug
Reporter: Zoltan Haindrich
Assignee: Zoltan Haindrich
In statements like {{struct(a,b) IN (const struct('x','y'), ... )}} the
comparision in UDFIn may fail because if a or b is of char/varchar type the
constants will retain string type - especially after PointlookupOptimizer
compaction.
