Hi Doug
A config property wouldn't solve the problem, because using more than
one hypertable instance with default configuration the proxy names
still conflict. Nevertheless a config property would simplify the
configuration in such situations. It would be sufficient if the master
hostname is just part of the prefix something like this "rs-" +
<master hostname> + "-" + <#>; do you think this is still confusing?
It indicates a range server ("rs") and the master where it belongs to.
