> 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.
