Description

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.
