Pack your Flink program to JAR

cd ~/CUHK-CSE-Lab-Flink
mvn package

The jar should be under target/flinkStream-1.0-SNAPSHOT.jar

Copy to the JAR to your workstation. Execute this command:

scp <your cse account name>@node-1.cse.cuhk.edu.hk:CUHK-CSE-Lab-Flink/target/flinkStream-1.0-SNAPSHOT.jar ./

Now the flinkStream-1.0-SNAPSHOT.jar should be in your home directory.
