I've been trying to use the bulk indexer in an app we're writing, and we're finding that we need to be more intelligent about error handling. For instance, in our setup we point the app at a load balancer which redirects to our Elasticsearch nodes. If all nodes are down we get a 503 with some html, and the elastigo library returns this as a json parsing error.
I've put in some improvements for better error handling, and a unit test which more closely demonstrates our need.
