Stamatis Zampetakis updated HIVE-27760:
---------------------------------------
Summary: WHERE condition on DATE type partitioning column leads to wrong
results (was: Filter on date type partitioning column producing 0 results)
> WHERE condition on DATE type partitioning column leads to wrong results
> ------------------------------------------------------------------------
>
> Key: HIVE-27760
> URL: https://issues.apache.org/jira/browse/HIVE-27760
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Reporter: Dayakar M
> Assignee: Dayakar M
> Priority: Major
> Labels: pull-request-available
>
> Filter on date type partitioning columns producing 0 results.
> {*}Reproduction steps{*}:
> 1. test.q
> {noformat}
> CREATE EXTERNAL TABLE test(a string,b String) PARTITIONED BY(PartitionDate
> DATE) STORED AS ORC;
> INSERT into test(PartitionDate, a,b)
> VALUES('2023-01-01','2023-01-01','2023-01-01');
> INSERT into test(PartitionDate, a,b)
> VALUES('2023-01-02','2023-01-02','2023-01-02');
> select count(*) from test where PartitionDate = '2023-01-01';{noformat}
> 2. Command to execute (pass different timezone than server)
> {noformat}
> mvn test -Dtest=TestMiniTezCliDriver -Dqfile=test.q
> -Dtest.output.overwrite=true -Duser.timezone=Asia/Hong_Kong{noformat}
>
> *RootCause:* As a part of HIVE-27373 issue fix to parse the string to
> java.sql.Date object, java.text.SimpleDateFormat is replaced with
> java.time.format.DateTimeFormatter using java.time.LocalDate which represents
> a Date without TimeZone. Here this input is passed [here
> |https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/MetaStoreDirectSql.java#L1370]
> which uses SimpleDateFormat(parsing dates in a locale-sensitive manner) and
> java.sql.Date. Here user timezone is passed different so actual value is
> getting changed to a different value (for example 2023-01-01 is changed to
> 2022-12-31) which is not matching with any partition so nothing gets returned.
> *Solution:*
> 1. In MetaStoreDirectSql.java, we should use
> java.time.format.DateTimeFormatter with java.time.LocalDate so that it will
> return proper date string.
> Or
> 2. Revert the code changes(only formatter and LocalDate) done for HIVE-27373
> and use SimpleDateFormat and java.sql.Date.
