Also, how many machines are usually assigned the roles of gc, tracers, and monitor? Couldn't
find much about them (didn't see any mention of them in the configuration section of the documentation),
but I saw in the logs that my tservers were trying to connect to, so I replaced
localhost in conf/tracers with the master, which eliminated that 'connection refused' error.

I don't think it is.

You can have multiple masters: they have a distributed election via zookeeper and the winner
does coordination and the losers wait for the winner to die.

Updates to the documentation are cheerfully accepted. :-)

Does the documentation discuss what it means to have two masters in an Accumulo configuration?
