puzzled at the output
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>
