示例1: getServerHoldingRegion
import org.apache.hadoop.hbase.client.HConnection; //導入方法依賴的package包/類
@Override
public ServerName getServerHoldingRegion(byte[] regionName) throws IOException {
HConnection connection = admin.getConnection();
HRegionLocation regionLoc = connection.locateRegion(regionName);
