> In InputFormatSourceFunction.java:
> {code:java}
> OUT nextElement = serializer.createInstance();
> while (isRunning) {
> format.open(splitIterator.next());
> // for each element we also check if cancel
> // was called by checking the isRunning flag
> while (isRunning && !format.reachedEnd()) {
> nextElement =
> format.nextRecord(nextElement);
> if (nextElement != null) {
> ctx.collect(nextElement);
> } else {
> break;
> }
> }
> format.close();
> completedSplitsCounter.inc();
> if (isRunning) {
> isRunning = splitIterator.hasNext();
> }
> }
> {code}
> the format may return other element or null when nextRecord, that will may
> cause exception.
