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

["Owen O'Malley (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-5381?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Owen O'Malley updated HADOOP-5381:
----------------------------------

    Status: Open  (was: Patch Available)

This looks good, but a few minor points:
  1. getBlkIndex should be removed and inlined into getBlockIndex.
  2. it seems like the first block processing can be rolled into the loop in getSplitHosts.
  3. HostInfo should use long instead of LongWritable, since there is no need for serialization.

> 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.
