> 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.
