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.
