> the current scheme for a checkpointing daemon to upload a merged fsimage
> file to an NN is to issue an HTTP get request to tell the target NN to issue
> another GET request back to the checkpointing daemon to retrieve the merged
> fsimage file. There's no fundamental reason the checkpointing daemon can't
> just use an HTTP POST or PUT to send back the merged fsimage file, rather
> than the double-GET scheme.
