INodeFileUnderConstruction 继承自INodeFile ,但是多了下面这六个类变量。都是在为了标示UnderConstruction状态时的一些必要的信息
class INodeFileUnderConstruction extends INodeFile
String clientName; // lease holder
private final String clientMachine;
private final DatanodeDescriptor clientNode; // if client is a cluster node too.
private int primaryNodeIndex = -1; //the node working on lease recovery
private DatanodeDescriptor[] targets = null; //locations for last block
private long lastRecoveryTime = 0;
