Description

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.
