我有这个密码：

public void reduce(Text key, Iterable<Text> values, Context context) 
        throws IOException, InterruptedException 
        {
            String name = null; 
            String sid = null;
            String predicate = null;
            String oid = null;
            String id = null;
            String outKey = null;
            String outVal = null;

            LinkedList<Text> valuesList = new LinkedList<Text>();
            Iterator<Text> ite = values.iterator();
            while(ite.hasNext()) {
                Text t = ite.next();
                String[] entities = t.toString().split("#-#-#-#");
                        if(entities[entities.length-1].equalsIgnoreCase("topic_name"))
                {
                    name = entities[0];
                }
                valuesList.add(t);
            }
            Iterator<Text> ite2 = valuesList.iterator();
            while(ite2.hasNext()) { 
                Text t2 = ite2.next(); 
                String[] entities = t2.toString().split("#-#-#-#");
                if(!entities[entities.length-1].contains("topic_name"))
                {
                     if(name!=null) {
                     outKey = entities[0]+"\t"+entities[1]+"\t"+name;
                }
                else 
                {
                    outKey = entities[0]+"\t"+entities[1]+"\t"+key.toString();
                }
                context.write(new Text(outKey), null);
                }
            }
        }

我看到，当我再次遍历这些值时，它总是获取缓存副本中的最后一个值。
