It's not possible to change it via Ambari, but it will populate the
variable appropriately. There's some translation magic happening somewhere,
because Ambari lists the value of nimbus.seeds as 'node1', but it actually
passes it down as a list (which is why the new commit doesn't surround it with
square brackets). I'm guessing this magic is also why the thrift config doesn't
get passed.
