Konstantin Shvachko commented on HADOOP-4045:
---------------------------------------------
I see also that {{incrementCheckpointTime()}} is not called on other occasions,
like
- {{EditLog.logEdit()}}
- {{EditLog.close()}}
- {{FSImage.rollFSImage()}}
If we don't increment fsTime for remaining directories, which is done by
{{incrementCheckpointTime()}}, we risk loosing data on name-node restart. I
think this is critical enough to be a blocker.
> Increment checkpoint if we see failures in rollEdits
