----------------------------------------------------------------------------------------
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.
