示例1: bootstrap

private void bootstrap(Collection<Token> tokens)
{
isBootstrapMode = true;
SystemKeyspace.updateTokens(tokens); // DON'T use setToken, that makes us part of the ring locally which is incorrect until we are done bootstrapping
if (!DatabaseDescriptor.isReplacing())
{
// if not an existing token then bootstrap

}
else

setMode(Mode.JOINING, "Starting to bootstrap...", true);
new BootStrapper(FBUtilities.getBroadcastAddress(), tokens, tokenMetadata).bootstrap(); // handles token update
logger.info("Bootstrap completed! for the tokens {}", tokens);
}
示例2: setTokens
import org.apache.cassandra.db.SystemKeyspace; //导入方法依赖的package包/类
/** This method updates the local token on disk */
public void setTokens(Collection<Token> tokens)
{
if (logger.isDebugEnabled())

setMode(Mode.NORMAL, false);
}
示例3: testRelocationSuccess
import org.apache.cassandra.db.SystemKeyspace; //导入方法依赖的package包/类
/** Use STATUS changes to trigger membership update and validate results. */
@Test
public void testRelocationSuccess() throws UnknownHostException
{
