> Java 8 behavior.
> --------------------------------------------------------------------------------------------
>
> Key: SPARK-36970
> URL: https://issues.apache.org/jira/browse/SPARK-36970
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Yang Jie
> Assignee: Yang Jie
> Priority: Major
>
> The `date_format` function has some behavioral differences when using JDK 8
> and JDK 17 as following:
> the result of {{select date_format('2018-11-17 13:33:33.333', 'B')}} in
> {{datetime-formatting-invalid.sql}} with Java 8 is:
> {code:java}
> -- !query
> select date_format('2018-11-17 13:33:33.333', 'B')
> -- !query schema
> struct<>
> -- !query output
> java.lang.IllegalArgumentException
> Unknown pattern letter: B
> {code}
> and with Java 17 the result is:
> {code:java}
> - datetime-formatting-invalid.sql *** FAILED ***
> datetime-formatting-invalid.sql
> Expected "struct<[]>", but got "struct<[date_format(2018-11-17
> 13:33:33.333, B):string]>" Schema did not match for query #34
> select date_format('2018-11-17 13:33:33.333', 'B'): -- !query
> select date_format('2018-11-17 13:33:33.333', 'B')
> -- !query schema
> struct<date_format(2018-11-17 13:33:33.333, B):string>
> -- !query output
> in the afternoon (SQLQueryTestSuite.scala:469)
> {code}
>
> From the javadoc we can find that 'B' is used to represent `{{Pattern letters
> to output a day period`}} in Java 17.
