Subject [jira] [Updated] (HDFS-4126) Add reading/writing snapshot information to FSImage
Date Sat, 12 Jan 2013 21:16:12 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4126?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jing Zhao updated HDFS-4126:

    Attachment: HDFS-4126.001.patch

Initial patch. Also integrate the fsimage saving/loading into TestSnapshot#testSnapshot. Still
have a bug when handling INodeFileLink and INodeFileSnapshot, which may cause testSnapshot
to fail after running ~10 iterations. Will update the patch after fixing the bug.
