Weiwei Yang commented on YARN-9057:
-----------------------------------

would ever move existing jars. Let me check, thanks!

> CSI jar file should not bundle third party dependencies

> hadoop-yarn-csi-3.3.0-SNAPSHOT.jar bundles all third party classes like a 
> shaded jar instead of CSI only classes.  This is generating error messages 
> for YARN cli:
> {code}
> SLF4J: Class path contains multiple SLF4J bindings.
> SLF4J: Found binding in 
> [jar:file:/usr/local/hadoop-3.3.0-SNAPSHOT/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

> [jar:file:/usr/local/hadoop-3.3.0-SNAPSHOT/share/hadoop/yarn/hadoop-yarn-csi-3.3.0-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]
> SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an 
> explanation.
