Subject [jira] Commented: (HADOOP-3948) Separate Namenodes edits and fsimage
Date Tue, 19 Aug 2008 18:03:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12623748#action_12623748

Lohit Vijayarenu commented on HADOOP-3948:

_FSEditLog::processIOError(int)_ removes the stream and directory like this

how about changing _fsimage.processIOError_ to accept File descriptor to take care of cleanup.
Since directory handling is done at FSImage level, EditOutputStream need not worry about it.
We could add an additional call to get File descriptor from EditFileOutputStream

> NameNode's _edits_ and _fsimage_ should be separated with an option of having them in
their own separate directories.
