Hi, @fhueske I have some small questions here. I can see that there are
some jar files in the example folder(```$FLINK_DIR/example```), some jar files
in the ```$FLINK_DIR/lib``` folder, and other jar files in the
```$FLINK_DIR/opt``` folder. Why did you copy this jar file from opt folder to
lib folder, instead of putting to ```$FLINK_DIR/example``` ? Thanks.
