Kihwal Lee commented on HADOOP-4885:
------------------------------------
- It would be better if the resyncing up to the last closed edit log is done
asynchronously. That way, the NN only needs to sync one or two edits while
rolling the log.
- It seems that if a restore fails, rollEditLog() also fails even if there are
healthy directories. Ideally any exceptions from dealing with the removed dirs
should be ignored.
> Try to restore failed replicas of Name Node storage (at checkpoint time)
