Description

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.
