org.apache.zookeeper.server.quorum.FastLeaderElection
Implementation of leader election using TCP. It uses an object of the class QuorumCnxManager to manage connections. Otherwise, the algorithm is push-based as with the other UDP implementations. There are a few parameters that can be tuned to change its behavior. First, finalizeWait determines the amount of time to wait until deciding upon a leader. This is part of the leader election algorithm.
