Cheolsoo Park commented on PIG-3457:
------------------------------------
Thank you Daniel for taking care of this. Two questions:
1) Can we commit this only to branch-0.12? We don't need to carry this on in
0.13, do we?
2) I don't seem to understand why it's necessary for JobStats class to have the
private MRJobStats member while it extends MRJobStats. Can you help me to
understand this?
{code}
public class JobStats extends MRJobStats {
+ MRJobStats jobStats;
public JobStats(String name, JobGraph plan) {
super(name, plan);
}
+ public JobStats(MRJobStats mrJobStats) {
+ super(mrJobStats.getName(), (JobGraph)mrJobStats.getPlan());
+ this.jobStats = mrJobStats;
+ }
+
+ @Override
+ public JobState getState() { return jobStats.getState(); }
...
{code}

> 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.
