示例1: bootstrap
import org.apache.cassandra.dht.BootStrapper; //导入依赖的package包/类
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
List<Pair<ApplicationState, VersionedValue>> states = new ArrayList<Pair<ApplicationState, VersionedValue>>();
states.add(Pair.create(ApplicationState.TOKENS, valueFactory.tokens(tokens)));
states.add(Pair.create(ApplicationState.STATUS, valueFactory.bootstrapping(tokens)));
Gossiper.instance.addLocalApplicationStates(states);
setMode(Mode.JOINING, "sleeping " + RING_DELAY + " ms for pending range setup", true);
Uninterruptibles.sleepUninterruptibly(RING_DELAY, TimeUnit.MILLISECONDS);
}
else
{
// Dont set any state for the node which is bootstrapping the existing token...
tokenMetadata.updateNormalTokens(tokens, FBUtilities.getBroadcastAddress());
SystemKeyspace.removeEndpoint(DatabaseDescriptor.getReplaceAddress());
}
if (!Gossiper.instance.seenAnySeed())
throw new IllegalStateException("Unable to contact any seeds!");
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: resetGcGraceSeconds
import org.apache.cassandra.dht.BootStrapper; //导入依赖的package包/类
@Before
public void resetGcGraceSeconds()
{

InetAddress local = FBUtilities.getBroadcastAddress();

for (CFMetaData table : Schema.instance.getTablesAndViews(KEYSPACE))
