> In stress testing failover, I had the following failure:
> - NN1 rolls edit logs and starts writing edits_inprogress_1000
> - NN1 crashes before writing the START_LOG_SEGMENT transaction
> - NN2 tries to become active, and calls {{recoverUnfinalizedSegment}}. Since
> the log file contains no valid transactions, it is marked as corrupt and
> renamed with the {{.corrupt}} suffix
> - The sanity check in {{openLogsForWrite}} will refuse to open a new
> in-progress log at the same txid. Failover does not proceed.
