Subject [jira] Commented: (HADOOP-1549) All remaining UTF8 data structures in HDFS code should be removed
Date Thu, 17 Apr 2008 22:57:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12590232#action_12590232

Edward J. Yoon commented on HADOOP-1549:
----------------------------------------

Thanks for advice, raghu and konstantin.

{quote}So I recommend just to remove UTF8 for everything but the storage classes, like Storage,
FSImage, FSEditLog, DataStorage. {quote}

I see. Then, Is there no necessity for upgrade of older image? or Should we keep old image
for version migration?
