---------------------------------------
+1, Patch looks good. May be we should have some test cases around counters as
well.

> A NPE is thrown when KafkaSource calls counter.incrementKafkaEmptyCount()
> because it expects MonitoredCounterGroup.counterMap to contain key
> "source.kafka.empty.count". A patch is included which adds this key to the
> ATTRIBUTES string array, which is used to pre-populate keys with an initial
> value.
