### What changes were proposed in this pull request?
**RootCause:** As a part of [HIVE-27373](http://example.com/) 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:** We can revert back the code to use SimpleDateFormat with
java.sql.Date to avoid the issue..
