示例1: populateSnapshots
import org.apache.kafka.common.PartitionInfo; //導入方法依賴的package包/類
private void populateSnapshots(Cluster kafkaCluster,
ClusterModel clusterModel,
TopicPartition tp,
Snapshot[] leaderLoadSnapshots) throws ModelInputException {
PartitionInfo partitionInfo = kafkaCluster.partition(tp);
// If partition info does not exist, the topic may have been deleted.
if (partitionInfo != null) {
for (Node replica : partitionInfo.replicas()) {
boolean isLeader = partitionInfo.leader() != null && replica.id() == partitionInfo.leader().id();
String rack = getRackHandleNull(replica);
// Note that we assume the capacity resolver can still return the broker capacity even if the broker
// is dead. We need this to get the host resource capacity.
Map<Resource, Double> brokerCapacity =
_brokerCapacityConfigResolver.capacityForBroker(rack, replica.host(), replica.id());
clusterModel.createReplicaHandleDeadBroker(rack, replica.id(), tp, isLeader, brokerCapacity);
// Push the load snapshot to the replica one by one.
for (int i = 0; i < leaderLoadSnapshots.length; i++) {
clusterModel.pushLatestSnapshot(rack, replica.id(), tp,
isLeader ? leaderLoadSnapshots[i].duplicate() : MonitorUtils.toFollowerSnapshot(leaderLoadSnapshots[i]));
}
}
}
