Subject [jira] [Created] (MAPREDUCE-4941) Use of org.apache.hadoop.mapred.lib.CombineFileRecordReader requires casting
Date Mon, 14 Jan 2013 22:36:12 GMT
Jason Lowe created MAPREDUCE-4941:
-------------------------------------

             Summary: Use of org.apache.hadoop.mapred.lib.CombineFileRecordReader requires
casting
                 Key: MAPREDUCE-4941
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4941
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.23.5, 2.0.2-alpha
            Reporter: Jason Lowe
            Priority: Minor


Unlike its counterpart in org.apache.hadoop.mapreduce.lib.input, the CombineFileRecordReader
in mapred requires a user to cast to a RecordReader since the constructor specification says
it must have the RecordReader<K,V> class as a parameter.  It should use {{Class<?
extends RecordReader<K,V>>}} like its mapreduce counterpart to make it easier to
use.
