               throws java.io.IOException

Throws:

java.io.IOException

getBootstrapToken

public static Token getBootstrapToken(TokenMetadata metadata,
                                      java.util.Map<java.net.InetAddress,java.lang.Double> load)

                                      ConfigurationException

if initialtoken was specified, use that. otherwise, pick a token to assume half the load of the most-loaded node.

Throws:

java.io.IOException

ConfigurationException

getBalancedToken

public static Token getBalancedToken(TokenMetadata metadata,
                                     java.util.Map<java.net.InetAddress,java.lang.Double> load)
