Reducer should not be abstract in order to serve as substitute for IdentityReducer ----------------------------------------------------------------------------------
Key: MAPREDUCE-724 URL: https://issues.apache.org/jira/browse/MAPREDUCE-724 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 0.20.1 Reporter: Sean Owen Priority: Minor The old IdentityReducer class has been deprecated since the new Reducer class's default behavior is the very same. The @deprecated tag indicates Reducer is a substitute. However it is an abstract class and cannot be instantiated, which causes problems. I imagine it is just a matter of removing the 'abstract' keyword. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
