Subject [jira] Commented: (HADOOP-4963) Logs saying org.apache.hadoop.util.DiskChecker$DiskErrorException in TaskTracker are not relevant
Date Wed, 06 Jan 2010 19:30:54 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12797263#action_12797263
] 

Konstantin Boudnik commented on HADOOP-4963:
--------------------------------------------

I'm ready to merge this modification back to 0.19 (sorry, it took me a bit longer to get there).
I'm wondering though what should be done wrt CHANGES.txt file? The 0.19.2 has been released
and we are clearly aren't suppose to _add_ anything to its list of fixes. What is the common
practice about backport of fixes to already released versions?
