-------------------------------------
Hi,
I checked the patch, it seems you are simply grabbing standard counters for the
purpose. Did you know you can simply write out all counters with
LOG.info(currentJob.getCounters())
The best way for the purpose of this issue is to simply make a custom counter.
So for every url injected (every context.write() call) you call something like:
context.getCounter("injector", "urls_injected").increment(1);
Then outputting this count at the end of the job is trivial. You could output
all counters (like stated above) or only the "injector" group, whatever pleases
you.
