示例1: reloadGossiperState
import org.apache.cassandra.gms.Gossiper; //导入方法依赖的package包/类
private void reloadGossiperState()
{
if (Gossiper.instance != null)
{
ReconnectableSnitchHelper pendingHelper = new ReconnectableSnitchHelper(this, myDC, preferLocal);
Gossiper.instance.register(pendingHelper);
pendingHelper = snitchHelperReference.getAndSet(pendingHelper);
if (pendingHelper != null)
Gossiper.instance.unregister(pendingHelper);
}
// else this will eventually rerun at gossiperStarting()
}
示例2: waitForSchemaAgreement
import org.apache.cassandra.gms.Gossiper; //导入方法依赖的package包/类
private int waitForSchemaAgreement(InetAddress endpoint) throws TimeoutException
{
Gossiper gossiper = Gossiper.instance;
int waited = 0;
// first, wait for schema to be gossiped.
while (gossiper.getEndpointStateForEndpoint(endpoint) != null && gossiper.getEndpointStateForEndpoint(endpoint).getApplicationState(ApplicationState.SCHEMA) == null)

// usually we use DD.getDefsVersion, which checks the local schema uuid as stored in the system keyspace.
// here we check the one in gossip instead; this serves as a canary to warn us if we introduce a bug that
// causes the two to diverge (see CASSANDRA-2946)
