Raft leader election implementation

Raft Leader Election Implementation

Config file

The configuration file indicates (1) how many instances of your server will run, (2) where those instances are running. The config file looks like:

N: 4
node0: <host>:<port>
node1: <host>:<port>
node2: <host>:<port>
node3: <host>:<port>

N specifies the number of nodes, which can be up to 9. Then there is a line for each node, starting at 0 and going up to (N-1).

Running the program

The program should take two arguments: the first is the location of the configuration file, and the second is an indication of which node the program represents. For example:

$ python3 raftnode.py ./myconfig.txt 3

would start node 3

Timing

When a majority of the nodes are up and running and can communicate with each other, one of those nodes can be elected as leader within 5 seconds.
