Counter MAP_INPUT_BYTES missing from new mapreduce api.
-------------------------------------------------------
Key: HADOOP-5710
URL: https://issues.apache.org/jira/browse/HADOOP-5710
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Amareshwari Sriramadasu
Assignee: Amareshwari Sriramadasu
Fix For: 0.21.0
MapTask, with current new mapreduce api, does not maintain MAP_INPUT_BYTES
counter. Since RecordReader doesnot have getPos() api, it is not possible for
the map task to maintain. Individual record readers (LineRecordReader,
SequenceFileRecordReader) could be modified to maintain the same.
