Subject [jira] [Updated] (HDFS-1073) Simpler model for Namenode's fs Image and edit Logs
Date Wed, 06 Apr 2011 22:54:06 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1073?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-1073:
------------------------------

    Attachment: hdfs1073.pdf

Updated most of the design doc to reflect the transaction-ID based naming. There are a few
bits (eg test plan and backupnode operation) that still need to be updated to reflect the
current plan, but this should be helpful to reviewers looking at the branch as it is today.
