Subject [jira] [Commented] (HDFS-1580) Add interface for generic Write Ahead Logging mechanisms
Date Thu, 26 May 2011 17:05:48 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13039788#comment-13039788

Todd Lipcon commented on HDFS-1580:

Hey Ivan - yes, I agree that using the number of bytes is a bit lame, and it would be much
nicer to be able to "recover" the inprogress files and properly rename them to an edits_N-M
type "finalized" file at startup time. I think in fact there is a related bug which I commented
about [here| https://issues.apache.org/jira/browse/HDFS-1896?focusedCommentId=13035976&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13035976]

I'll take a look at HDFS-2003
