Subject [jira] Commented: (HADOOP-4045) Increment checkpoint if we see failures in rollEdits
Date Wed, 04 Feb 2009 02:09:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12670215#action_12670215
] 

Konstantin Shvachko commented on HADOOP-4045:
---------------------------------------------

This should include some cleanup. We have at least for different methods called {{processIOError()}}.
It would be nice to reduce the number just to 2
- {{FSImage.processIOError()}} and
- {{FSEdits.processIOError()}}

> In _FSEditLog::rollEdits_, if we encounter an error during opening edits.new, we remove
 the store directory associated with it. At this point we should also increment checkpoint
on all other directories.
