Subject [jira] Commented: (HDFS-553) BlockSender reports wrong failed position in ChecksumException
Date Wed, 26 Aug 2009 21:07:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12748149#action_12748149

dhruba borthakur commented on HDFS-553:
---------------------------------------

I propose that we backport this to 0.20? This is a very simple and row risk fix and helps
applications that depend on the correct offset being recorded inside Checksumexception. If
folks agree, then I will pull this into 0.20 as well.
