Heya,
We just released Twitter River plugin 1.4.0 for Elasticsearch: https://github.com/elasticsearch/elasticsearch-river-twitter
Basically, we disabled login / password as removed by Twitter: #28
You must use now OAuth.
Full list is here: https://github.com/elasticsearch/elasticsearch-river-twitter/issues?labels=1.4.0&page=1&state=closed
Have fun!
