--------------------------------------------
This means that Hive users that will upgrade to JDK11 may observe behavior
changes when using the SQL functions outlined. Many thanks for this analysis,
it will be helpful for people doing upgrades.
> Post JDK11: Local Test Failures for TestGenericUDFFromUnixTimeEvaluate and
> TestMiniLlapLocalCliDriver.udf_date_format.q

> Key: HIVE-28538
> URL: https://issues.apache.org/jira/browse/HIVE-28538
> Project: Hive
> Issue Type: Bug
> Security Level: Public(Viewable by anyone)
> Reporter: shivangi
> Assignee: shivangi
> Priority: Major
>
> *Issue:*
> Post JDK11, there are test failures occurring locally in the following test
> classes:
> # {{TestGenericUDFFromUnixTimeEvaluate}}
> # {{TestMiniLlapLocalCliDriver.udf_date_format.q}}
> *Error:*
> * *from_unixtime(1689930780, yyyy-MM-dd HH:mmaa) sessionZone=Etc/GMT,
> formatter=SIMPLE expected:<2023-07-21 09:13[AM]> but was:<2023-07-21
> 09:13[am]>*
> *Root Cause Analysis (RCA):*
> In JDK11, changes were made to the Java locale handling as documented in the
> following issues:
> * [JDK-8145136|https://bugs.openjdk.org/browse/JDK-8145136]
> * [JDK-8211985|https://bugs.openjdk.org/browse/JDK-8211985]
> These changes result in different locale behaviors. This issue does not occur
> in Jenkins because the test cases are written according to the {{en_US}}
> locale. However, when run locally, the locale may differ (e.g.,
> {{{}en_IN{}}}), causing discrepancies. For instance, {{en_IN}} would expect
> {{am/pm}} while the tests expect {{{}AM/PM{}}}, leading to failures.
> *Solution:*
> To ensure consistent behavior across both local and Jenkins environments,
> pass the locale in {{<maven.test.jvm.args>}} to align both environments to
> {{en_US.}}
> This will ensure that all tests run with the {{en_US}} locale, mitigating
> locale-related test failures.
>
> *Additional Notes:*
> * There may be other test failures not yet captured due to different locales
> in local environments. Ensure all tests run with the {{en_US}} locale to
> identify and resolve any further issues.
