Considerations to decide cluster majority in the event of a network partition:
Odd number of cluster nodes in the current membership: One sub-cluster gets majority upon a network split.
Even number of cluster nodes in the current membership: In case of an even network split, both the sub-clusters have equal number of nodes. The partition with the leader node is treated as majority and that partition survives.
In case of an uneven network split, such that one sub-cluster has more number of nodes than other sub-clusters, the majority sub-cluster gets majority and survives.
