Cheolsoo Park commented on PIG-3457:
------------------------------------
I think there are 2 changes:
# Changes JobStats to JobStatsBase and PigStatsUtil to PigStatsUtilBase. This
requires many changes in many places where JobStats and PigStatsUtil are used.
# Adds dummy classes JobStats and PigStatsUtil that extends MRJobStats and
MRPigStatsUtil respectively, so Oozie still can work without changing
PigStatsUtil to MRPigStatsUtil.
> Provide backward compatibility for PigStatsUtil and JobStats

> PIG-3419 restructured PigStatsUtil which break downstream projects such as
> Oozie. Oozie uses PigStatsUtil.{HDFS_BYTES_WRITTEN, MAP_INPUT_RECORDS,
> MAP_OUTPUT_RECORDS, REDUCE_INPUT_RECORDS, REDUCE_OUTPUT_RECORDS}. We need to
> provide a backward compatible way.
