This is an implementation of the Hirschberg and Sinclair algorithm for leader election in a ring using Finagle for RPCs.
This was done as a hack project and not meant to be used in production anywhere.
It currently has all servers and clients setup on localhost on different ports on localhost
To run, define a ring of servers via
$ sbt "electionLeader/runMain com.leader.election.electionLeaderFinagle PP ID NUM_NODES"
where PP is the ending of the port of the server that will run on port 80PP and ID is an integer for
the Id of the server and NUM_NODES is the number of nodes in the ring.
For example, to setup a ring of three serves on ports 8000, 8001, 8002 with ids 10, 11, 12 run
$ sbt "electionLeader/runMain com.leader.election.Main 00 10 3"
$ sbt "electionLeader/runMain com.leader.election.Main 01 11 3"
$ sbt "electionLeader/runMain com.leader.election.Main 02 12 3"
in three different terminal sessions.
