Ashutosh Chauhan commented on HIVE-8099:
----------------------------------------
Backported to 0.14
> IN operator for partition column fails when the partition column type is DATE
> -----------------------------------------------------------------------------
>
> Key: HIVE-8099
> URL: https://issues.apache.org/jira/browse/HIVE-8099
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.13.0, 0.13.1
> Reporter: Venki Korukanti
> Assignee: Venki Korukanti
> Fix For: 0.15.0, 0.14.1
>
> Attachments: HIVE-8099-ppr-fix.patch, HIVE-8099.1.patch,

> Test table DLL:
> {code}
> CREATE TABLE testTbl(col1 string) PARTITIONED BY (date_prt date);
> {code}
> Following query used to work fine in Hive 0.12 as the constant types are
> 'string' and partition column type is considered as 'string' throughout the
> planning and optimization (including partition pruning).
> {code}
> SELECT * FROM testTbl WHERE date_prt IN ('2014-08-09', '2014-08-08');
> {code}
> In trunk the above query fails with:
> {code}
> Line 1:33 Wrong arguments ''2014-08-08'': The arguments for IN should be the
> same type! Types are: {date IN (string, string)}
> {code}
> HIVE-6642 changed the SemanticAnalyzer.java to consider partition type given
> in table definition instead of hardcoded 'string' type. (Modified [Hive 0.12
> code|https://github.com/apache/hive/blob/branch-0.12/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java#L7778]).
> So changed the query as follows to go past the above error:
> {code}
> SELECT * FROM testTbl WHERE date_prt IN (CAST('2014-08-09' AS DATE),
> CAST('2014-08-08' AS DATE));
> {code}
> Now query goes past the error in SemanticAnalyzer, but hits the same issue
> (default 'string' type for partition columns) in partition pruning
> optimization. (Realted code
> [here|https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/optimizer/ppr/PartExprEvalUtils.java#L110]).
>
> {code}
> 14/09/14 20:07:20 ERROR ql.Driver: FAILED: SemanticException
> MetaException(message:The arguments for IN should be the same type! Types
> are: {string IN (date, date)})
> {code}
> We need to change partition pruning code to consider the partition column as
> the type given in table definition.
