Brandon Li commented on HDFS-3576:
----------------------------------
{quote}This patch appears to have just shifted the hardcoded value. Would it
maybe be cleaner to have a Namenode.getDefaultPort() to return the value? That
would provided a single point of change in case we actually want to obtain the
default port from the conf as is done for other ports.{quote}
Daryn, thanks for looking into the patch. Since it is the "default" port, it
doesn't need to be configured in conf. DFSConfigKeys has become the place to
save this kind of configuration constants. Not sure if I answered your question.

> Currently the default rpc port (8020) is hard coded in NameNode.java, which
> makes it inconvenient to locate.
