Description

When setting YarnConfigOptions#CLASSPATH_INCLUDE_USER_JAR to "LAST", I think the user jars should come after all flink libs&jars in runtime classpath, including "flink.jar".

But actually it's not:

org.apache.flink.yarn.AbstractYarnClusterDescriptor#startAppMaster

I'm not sure if it's an expected behavior, because if a user forgets to mark Flink dependencies as "provided", it causes conflicts in detached mode.
