Guys, have been stretching my head for the past couple of days.  Why are my 
tags duplicated while the content they wrap around i.e.my  StringBuilder sb is 
not?


My Reduce code is:
while (values.hasNext()){
    sb.append(values.next().toString());
   }
    output.collect(key,new Text("\n<aaa>\n"+sb.toString()+"\n</bbbb>\n" ));

The out put:
2459
<aaa>

<aaa>
        <value....
                .....
                ......
</bbbb>

</bbbb>
