If we change nodeHttpAddress to empty string in RMWebServices.java, then it
conflicts with the way we have been displaying it in the UI, as we have been
displaying it as "N/A" for inactive nodes. Or do we need to capture this
behaviour some where in the documentation?

its ok for the webui to display something slightly different then the web
services. The UI should be "pretty and appealing to users" where as the web
services should be programmatic. In my opinion, the empty string would be more
programmatic and the N/A more user appealing. I will make sure to document
what empty fields mean in MAPREDUCE-3549.

After this change, if we provide true totalNodes info through web services, do
we need to provide the same info on the UI also?.
{quote}
I don't have a strong opinion either way. I guess it would be nice if ops or
someone wanted at quick glance to see total nodes to have it in the web ui.
My only concern would be if it makes the page to wide.
In general, the web services should include everything the web ui does but I
don't think it strictly necessarily to have everything from web services in the
web ui though. The main reason I say to leave totalNodes in the webservices is
because that field was already there and I would like to stay away from
removing fields unless we change the version number.
