Stamatis Zampetakis updated HIVE-27760:
---------------------------------------
Description:
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:* In MetaStoreDirectSql.java, we should use
java.time.format.DateTimeFormatter with java.time.LocalDate so that it will
return proper date string.
