HI there Gunnar- hbase-site.xml is only there to get the number of and name of the zookeeper nodes (look at dcs-installer and you will see how it is used). This file can be deleted after its used, but figured it wouldn't hurt to keep it around.
From what I understand, the upgrade must be done from the same node as the initial install was made because /etc/trafodion and /usr/bin/trafodion contains more information than on the other nodes? It shouldn't "have to be" everything should be current on all nodes in regards to /etc/trafodion and /usr/bin/trafodion. With that said, I believe we normally test this way ... so there may be bugs. a --config_file, then you reuse it. Can you change it to combine a configuration change; for example, add new nodes? Yes, absolutely.
