> The 2NN will avoid downloading/loading a new fsimage if its local copy of
> fsimage is the same as the version on the NN. However, the decision to *load*
> the fsimage from disk into memory is based only on the on-disk fsimage
> version. If an error occurs between downloading and loading the fsimage on
> the first checkpoint attempt, the 2NN will never load the fsimage, and then
> on subsequent checkpoint attempts it will not load the on-disk fsimage and
> thus will never checkpoint successfully.
> Example error message in the first comment of this ticket.
