[jira] Commented: (HADOOP-5381) Extend HADOOP-3293 to MapReduce package also

    [ https://issues.apache.org/jira/browse/HADOOP-5381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678643#action_12678643 ] 

dhruba borthakur commented on HADOOP-5381:
------------------------------------------

Another option is to use CombineFileInputFormat. In the long run, it might be possible to subsume the behaviour of FileInputFormat by CombineFileInputFormat.

> HADOOP-3293 made changes to FileInputFormat to identify split locations that contribute most to the split. This functionality has to be added to the MapReduce.FileInputFormat too.
