use List in reducer

[oo famcr]

Hello everyone
I want to save the value to a LinkedList, but THE ***activeList.get(0)***
have been changed every time.
I think it should be the first element, but it's not

Thanks

  public static class IntSumReducer
       extends Reducer<Text,Text,Text,Text> {
    private List<Text> activeList = new LinkedList<Text>();
    public void reduce(Text key, Iterable<Text> values,
                       Context context
                       ) throws IOException, InterruptedException {
      for (Text val : values) {
        activeList.add(val);
        context.write(key, new Text(  activeList.get(0).toString()  ));
      }
    }
