Subject [jira] [Updated] (MAPREDUCE-4941) Use of org.apache.hadoop.mapred.lib.CombineFileRecordReader requires casting
Date Mon, 15 Apr 2013 18:14:16 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4941?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Karthik Kambatla updated MAPREDUCE-4941:
----------------------------------------

    Attachment: MAPREDUCE-4941.patch

The patch looks good to me. Wonder what the release audit problems are, re-uploading the patch
to force a Jenkins run.

> 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.
