[jira] [Resolved] (HADOOP-2628) the combiner output counter is really counting number of input keys to the combiner

     [ https://issues.apache.org/jira/browse/HADOOP-2628?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Harsh J resolved HADOOP-2628.
-----------------------------

    Resolution: Not A Problem

This was resolved at some point in history. We have proper in/out counters and tests for it today.

> Currently, each key that is read by the combiner bumps the number of combiner outputs. We should have both combiner input keys and combiner output record counters.
