Subject [jira] Commented: (HDFS-1496) TestStorageRestore is failing after HDFS-903 fix
Date Tue, 01 Feb 2011 08:49:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12989099#comment-12989099
] 

Hairong Kuang commented on HDFS-1496:
-------------------------------------

Here is the inconsistency that is introduced by HADOOP-4885. After failed directories are
added back, each failed directory contains new image + zero edit while each old good directory
contains old image + old edit. If secondary namenode happens to fetch the image from a failed
directory but fetch the edit from an old good directory, how would checkpointing work.
