Hey Jeremy, future versions of Graylog2 allow you to do this automatically but for now you'll indeed have to move all shards over to a node you are not going to shut down. Make sure to turn off auto-rebalancing first or ElasticSearch will immediately start to move over other shards.
Note that you can also configure Graylog2 to create replicas of each shard. This way you could turn off the second node completely without interrupting or moving anything by hand.
