------------------------------------
Summary: IsolatedClientLoader.isSharedClass return unindented
results of `slf4j` keyword
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
{{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")}}
