メソッドの詳細

minimumMasterNodes

public void minimumMasterNodes(int minimumMasterNodes)

minimumMasterNodes

public int minimumMasterNodes()

hasEnoughMasterNodes

public boolean hasEnoughMasterNodes(Iterable<DiscoveryNode> nodes)

sortByMasterLikelihood

public List<DiscoveryNode> sortByMasterLikelihood(Iterable<DiscoveryNode> nodes)

Returns the given nodes sorted by likelyhood of being elected as master, most likely first. Non-master nodes are not removed but are rather put in the end

nextPossibleMasters

public DiscoveryNode[] nextPossibleMasters(com.carrotsearch.hppc.ObjectContainer<DiscoveryNode> nodes,
                                           int numberOfPossibleMasters)

Returns a list of the next possible masters.

electMaster

public DiscoveryNode electMaster(Iterable<DiscoveryNode> nodes)

Elects a new master out of the possible nodes, returning it. Returns null if no master has been elected.
