Subject [jira] [Commented] (HDFS-1955) HDFS-1826 made FSImage.doUpgrade() too fault-tolerant
Date Thu, 30 Jun 2011 18:18:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13057966#comment-13057966
] 

Matt Foley commented on HDFS-1955:
----------------------------------

Looking at the Jenkins log, the javadoc complaint is:
[javadoc] javadoc: warning - Error fetching URL: http://java.sun.com/javase/6/docs/api/package-list
This is unrelated to the patch.

Committing.  Thanks, Daryn, for the review!

> Prior to HDFS-1826, doUpgrade() would fail if any of the storage directories failed to
successfully write the new fsimage or edits files.
> Now it appears to "succeed" even if some or all of the individual directories fail.
> There is some discussion about whether doUpgrade() should have some fault tolerance,
but for now make it fail on any single storage directory failure, as before.
