Allan Espinosa commented on HIVE-23700:
---------------------------------------
||hive-exec version||Result||
|3.1| ❌Occurs and aborts|
|4.2|✅ Occurs but proceeds|
This is the output when I uber-jar'ed hive-exec:4.2.0 with Spring Boot 4.2. As
you can see the stacktrace is still occurring but it proceeds to the next step
but reports "Found configuration file null"

The HiveConf object seem to have been initalized properly as I am able to use
it to connect to the Hive Metastore and do queries like listing my Hive tables.
> HiveConf static initialization fails when JAR URI is opaque

> Key: HIVE-23700
> URL: https://issues.apache.org/jira/browse/HIVE-23700
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 2.3.7
> Reporter: Francisco Guerrero
> Assignee: Francisco Guerrero
> Priority: Minor
> Labels: pull-request-available
> Attachments: HIVE-23700.1.patch
>
> Original Estimate: 120h
> Time Spent: 2h
> Remaining Estimate: 118h
>
> HiveConf static initialization fails when the jar URI is opaque, for example
> when it's embedded as a fat jar in a spring boot application. Then
> initialization of the HiveConf static block fails and the HiveConf class does
> not get classloaded. The opaque URI in my case looks like this
> _jar:file:/usr/local/server/some-service-jar.jar!/BOOT-INF/lib/hive-common-2.3.7.jar!/_
> HiveConf#findConfigFile should be able to handle `IllegalArgumentException`
> when the jar `URI` provided to `File` throws the exception.
> To surface this issue three conditions need to be met.
> 1. hive-site.xml should not be on the classpath
> 2. hive-site.xml should not be on "HIVE_CONF_DIR"
> 3. hive-site.xml should not be on "HIVE_HOME"
