Then, other nodes can join the group through the primary introducer node.We also predefined four potential introducers which ensure the rejoin of the primary introducer. These settings are in the Introuducers.java. The first one is the IP of primary introducer and the others are IPs of potential introducers. You can change them as you like.Our project is build on maven. You can package our project into a executeable jar file by the command mvn assembly:assembly. We assume that you name the jar file "mp2.jar". Then you can arrange the jar files at mahcines where you want to run the program.
