> In SortByShuffler.java, an ArrayList is used to back the iterator for values
> that have the same key in shuffled result produced by spark transformation
> sortByKey. It's possible that memory can be exhausted because of a large key
> group.
> {code}
> @Override
> public Tuple2<HiveKey, Iterable<BytesWritable>> next() {
> // TODO: implement this by accumulating rows with the same key
> into a list.
> // Note that this list needs to improved to prevent excessive
> memory usage, but this
> // can be done in later phase.
> while (it.hasNext()) {
> Tuple2<HiveKey, BytesWritable> pair = it.next();
> if (curKey != null && !curKey.equals(pair._1())) {
> HiveKey key = curKey;
> List<BytesWritable> values = curValues;
> curKey = pair._1();
> curValues = new ArrayList<BytesWritable>();
> curValues.add(pair._2());
> return new Tuple2<HiveKey, Iterable<BytesWritable>>(key,
> values);
> }
> curKey = pair._1();
> curValues.add(pair._2());
> }
> if (curKey == null) {
> throw new NoSuchElementException();
> }
> // if we get here, this should be the last element we have
> HiveKey key = curKey;
> curKey = null;
> return new Tuple2<HiveKey, Iterable<BytesWritable>>(key,
> curValues);
> }
> {code}
> Since the output from sortByKey is already sorted on key, it's possible to
> backup the value iterable using the same input iterator.
