I was not able to get this feature working as expected, with the following
job:
```java
public class URLClassloader {
public static void main(String[] args) throws Exception {
URL about = URLClassloader.class.getResource("/about.md");
System.out.println("about = "+about);
final StreamExecutionEnvironment see =
StreamExecutionEnvironment.getExecutionEnvironment();
see.addSource(new SourceFunction<Object>() {
@Override
public void run(SourceContext<Object> ctx) throws
Exception {
URL about =
this.getClass().getResource("/about.md");
System.out.println("about = "+about);
}
@Override
public void cancel() {}
});
see.execute();
}
}
```
invoking it like this
`./bin/flink run -c com.dataartisans.URLClassloader -C
file:///home/robert/flink-workdir/flink-irc-logs.github.io/
/home/robert/flink-workdir/debug-project-0.10/target/debug-project-0.10-1.0-SNAPSHOT.jar`
lead to the following output
```
./bin/flink run -c com.dataartisans.URLClassloader -C
file:///home/robert/flink-workdir/flink-irc-logs.github.io/
/home/robert/flink-workdir/debug-project-0.10/target/debug-project-0.10-1.0-SNAPSHOT.jar
about = file:/home/robert/flink-workdir/flink-irc-logs.github.io/about.md

about = null
about = null
about = null
about = null
about = null
```
So it seems that the client is using the correct classpath, and its able to
load the file. The JobManager/TaskManager (I've started flink with
start-local.sh) doesn't seem to be able to load the file.
