Change node settings at runtime

Is it possible to change node level settings at runtime? Specifically I'm looking to change node.data, node.master, and node.river.

No, this isn't possible. Changing those settings requires a restart of that
node.

How hard would it be to change this? Correct me if I'm wrong, but logically it shouldn't be a problem to change those settings at runtime as long as reallocation of shards or rivers (respectively) isn't currently happening. Is that fair?

Its actually quite tricky, since it might require a re-election of master
(relocation of data is simpler). Why would you need it thought? Those
settings would sound quite "static", as in if one goes with X masters and N
data nodes, one would probably keep on adding more data nodes.
