Two additional counters shouldn't be expensive. But do consider if the
already available "map input records" / "(map|reduce) output records"
suit your need for such counters.

I'm writing a load/store pair, and I am considering the use
of two Hadoop counters (via reporter). They would could the number
of records read/written, so that they would be available via
the job WebUI.
Is this an overly expensive proposition?
