Subject [jira] Updated: (HDFS-1538) Refactor more startup and image loading code out of FSImage
Date Wed, 15 Dec 2010 20:26:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-1538:
------------------------------

          Description: For HDFS-1073, we need to be able to continue to load images in the
old "fsimage/edits/edits.new" layout for the purposes of upgrade.  But that code will be only
for backwards compatibility, and we want to be able to switch to new code for the new layout.
This subtask is to separate out much of that code into an interface which we can implement
for both the old and new layouts.
    Affects Version/s: 0.23.0
                       0.22.0
