Ok, so HBase like Hadoop uses the hostname then goes to DNS to resolve the hostname.
If DNS is set up, does it skip /etc/hosts altogether, or depending on how DNS is set up, will
it eventually get to /etc/hosts?

And how often does the HBase master bind? Just once?

Sorry to jump in on this conversation, but I'm curious if there's any work to fix it so if
a machine is dual nic'd (two nics, each pointing to a different network) that you can specify
which nic you want to use for connectivity for a resource. (Imagine if you have a private
lan for the cloud and then an external interface.)
