> NN got killed while checkpointing in progress before renaming the ckpt file to actual
file.
> Since the checkpointing process is not completed, on next NN startup it will load previous
fsimage and apply rest of the edits.
> Functionally there's no harm but this ckpt file will be retained as is.
> Purger will not remove the ckpt file though other old fsimage files will be taken care.
