[jira] [Created] (MAPREDUCE-5231) Constructor of DBInputFormat.DBRecordReader in mapred is changed

Zhijie Shen created MAPREDUCE-5231:
--------------------------------------

             Summary: Constructor of DBInputFormat.DBRecordReader in mapred is changed
                 Key: MAPREDUCE-5231
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5231
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen


The constructor of DBInputFormat.DBRecordReader in mapred is changed from MR1 to RM2. Though MAPREDUCE-716 tried to deal with the API difference. However, if DBInputFormat.DBRecordReader is extended, the incompatibility around the constructor is still there.
