In the mapred api getRecordReader was passed a Reporter which could then
get passed to the RecordReader to allow a RecordReader to increment
counters for different types of records, bad records, etc. In the new
mapreduce api createRecordReader only gets the InputSplit and
TaskAttemptContext, both have no access to counters.

Is there really no way to increment counters inside of a RecordReader or
InputFormat in the mapreduce api?

Jim,

This is fixed in 2.x releases already via
https://issues.apache.org/jira/browse/MAPREDUCE-1905 (incompat
change). In 1.x this is a known limitation. Perhaps we can come up
with a different non-breaking fix for 1.x?
