  Hi,


  I can see that two new counters have been added for hive
 (RECORDS_IN/RECORDS_OUT) in hive 0.14.


  Prior to this release which counters could be used to get the records
 read by hive job and records written.  Because i noticed that in hive 0.14
 for a few hive jobs i see map_input_records but the map_output_records
 counter is 0 but the job actually writes something to output table and the
 hive log also gives that count correctly.


  In this case how else can we get records read and records written  in
 releases before 0.14.
