This could work.  On configuration update, we could write the
difference to the filesystem on each server.   We could write each
individual diff as its own file.  We could change the Configuration to
pick up hbase-site.xml + hbase-default.xml plus any edits made since
last restart (edits could be written to conf or to an edits dir?)

Or, move Configuration into zk altogether.
