Key: MAPREDUCE-1052
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1052
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Dick King
Fix For: 0.21.0


In my opinion, this was a change for the worse.

I would prefer to bring back the callback interface, at least in addition to the JobInfo interface, to give API users the option of not creating the whole object if they only want to glean part of the information.
