> As it stands, daemons which perform checkpointing must determine their own 
> address on which they can be reached, so that the NN which they checkpoint 
> against knows what address to fetch a merged fsimage from. This causes 
> problems if, for example, the daemon performing checkpointing binds to 
> 0.0.0.0, and thus can't be sure of what address the NN can reach it at.
