> Key: SPARK-23743
> URL: https://issues.apache.org/jira/browse/SPARK-23743
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Jongyoul Lee
> Priority: Minor
>
> {{isSharedClass}} returns if some classes can/should be shared or not. It
> checks if the classes names have some keywords or start with some names.
> Following the logic, it can occur unintended behaviors when a custom package
> has {{slf4j}} inside the package or class name. As I guess, the first
> intention seems to figure out the class containing {{org.slf4j}}. It would be
> better to change the comparison logic to {{name.startsWith("org.slf4j")}}
