示例1: getCurrentFreeClusterResources
import org.apache.hadoop.yarn.client.api.YarnClient; //導入方法依賴的package包/類
private ClusterResourceDescription getCurrentFreeClusterResources(YarnClient yarnClient) throws YarnException, IOException {
List<NodeReport> nodes = yarnClient.getNodeReports(NodeState.RUNNING);
int totalFreeMemory = 0;
int containerLimit = 0;
int[] nodeManagersFree = new int[nodes.size()];
for (int i = 0; i < nodes.size(); i++) {
NodeReport rep = nodes.get(i);
int free = rep.getCapability().getMemory() - (rep.getUsed() != null ? rep.getUsed().getMemory() : 0);
nodeManagersFree[i] = free;
totalFreeMemory += free;
if (free > containerLimit) {
containerLimit = free;
}
}
return new ClusterResourceDescription(totalFreeMemory, containerLimit, nodeManagersFree);
