                 Key: HDFS-3069
                 URL: https://issues.apache.org/jira/browse/HDFS-3069
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


In testing what happens in HA split brain scenarios, I ended up with an edits log that was
named edits_47-47 but actually had two edits in it (#47 and #48). The edits loading process
should detect this situation and barf. Otherwise, the problem shows up later during loading
or even on the next restart, and is tough to fix.
