UDF Counters

Hello everyone,

Is it possible to update a counter from within an UDF? I know there is some information on updating counters using log messages, but I have never done that before and have no idea if it is working with pig.

Thanks,

Daan.

This seems to work for me:

                       PigStatusReporter reporter =
PigStatusReporter.getInstance();
			if (reporter != null) {
			   reporter.getCounter("name", "group").increment(1);
			}
