Subject [jira] Updated: (MAPREDUCE-1480) CombineFileRecordReader does not properly initialize child RecordReader
Date Mon, 29 Mar 2010 23:15:28 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1480?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Aaron Kimball updated MAPREDUCE-1480:

    Attachment: MAPREDUCE-1480-branch20.patch

Attaching a patch for branch20. This applies cleanly on the Cloudera Distribution (CDH3),
which also includes a backport of MAPREDUCE-1423.

Since this is a bug in CombineFileInputFormat, this should be considered for application on
Apache 0.20.3.
