Subject [jira] Created: (HADOOP-3717) Provide tool to view/change edits file
Date Tue, 08 Jul 2008 20:12:31 GMT
Provide tool to view/change edits file
--------------------------------------

                 Key: HADOOP-3717
                 URL: https://issues.apache.org/jira/browse/HADOOP-3717
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
    Affects Versions: 0.19.0
            Reporter: Lohit Vijayarenu


At present if edits file is corrupt namenode fails to start throwing EOFException as seen
this this jira HADOOP-820. One way out in such cases was to remove offending entry from edits,
but that is not straight forward as edits is a binary file. So, workaround was to ignore EOFException
and continue with namenode startup. It would be good to have a tool to view edits entries
or even modify it to a recoverable state.
