示例1: internalGetTopBlockLocation
import org.apache.hadoop.hbase.regionserver.HRegion; //导入方法依赖的package包/类
/**
* Returns an ordered list of hosts that are hosting the blocks for this
* region. The weight of each host is the sum of the block lengths of all
* files on that host, so the first host in the list is the server which holds
* the most bytes of the given region's HFiles.
*
* @param region region
* @return ordered list of hosts holding blocks of the specified region
