Hello,
I need to collect some statistics using some of the counters defined by the
Map/Reduce framework such as "Reduce input records". I know I should use
the  getCounter method from Counters.Counter but I couldn't figure how to
use it. Can someone give me a two line example of how to read the values for
those counters and where I can find the names/groups of the predefined
counters?

Thanks in advance,
Jim
