Method Detail

bootstrap

public void bootstrap()

getBootstrapTokens

public static java.util.Collection<Token> getBootstrapTokens(TokenMetadata metadata,
                                             java.util.Map<java.net.InetAddress,java.lang.Double> load)
                                                      throws ConfigurationException

if initialtoken was specified, use that (split on comma). otherwise, if num_tokens == 1, pick a token to assume half the load of the most-loaded node. else choose num_tokens tokens at random

Throws:

ConfigurationException

getRandomTokens

public static java.util.Collection<Token> getRandomTokens(TokenMetadata metadata,
                                          int numTokens)
