[jira] Updated: (HDFS-1073) Simpler model for Namenode's fs Image and edit Logs

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

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

    Attachment: hdfs-1073-editloading-algos.txt

For anyone following along at home, I have most of the algorithms done for inspecting a set of storage dirs and deciding which sequence of images/logs to load. Attaching patch which applies on top of HDFS-1521 and HDFS-1538 but isn't actually integrated into FSImage yet - been relying on true unit tests for this so far.
