>             Project: Flink
>          Issue Type: Bug
>          Components: Deployment / YARN
>    Affects Versions: 1.8.1
>            Reporter: David Moravek
>            Assignee: David Moravek
>            Priority: Major

> Currently yarnship works as follows:
>  * user specifies directory to ship with the job
>  * yarn ships it with the container
>  * org.apache.flink.yarn.AbstractYarnClusterDescriptor#uploadAndRegisterFiles traverses directory recursively and adds each file to the classpath
> This works well for shipping jars, but doesn't work correctly with shipping resources that we want to load using java.lang.ClassLoader#getResource method.
> In order to make resource classloading work, we need to register it's directory instead of the file itself (java classpath expects directories or archives).
> CLASSPATH="shipped/custom.conf:${CLASSPATH}" needs to become CLASSPATH="shipped:${CLASSPATH}"
